Program. Then, after staying up in the sky the entire night, Mars sets in the west just as the sun rises in the east. Mars remains visible in the weeks following close approach, but becomes fainter as Mars and Earth travel farther away from each other in their orbits around the Sun. They will best know the preferred format. If that were true, we'd be in big trouble given the gravitational pulls on Earth, Mars, and our Moon! When Mars and Earth are at their closest, you have your launch window. Other civilizations also named the planet for this attribute for example, the Egyptians called it "Her Desher," meaning "the red one." Hubble space telescope imaging and spectroscopy of Mars during the extremely close approach of 2003, We need more rules for space junk and moon bases, NASA and US officials say, NASA's SWOT water satellite suffers instrument shutdown in orbit, NASA's IBEX spacecraft not responding to commands after computer glitch during 15-year mission to study interstellar border, Intense solar storm supercharges auroras over UK and more (photos), Pictures from space! celestial body that is nearly spherical but does not meet other definitions for a planet. Heres an example of recent Missions to Mars, and the years they launched: See the trend? It's only larger than Mercury, which has a diameter of about 3,032 miles, per NASA. Mars is at its closest to Earth until 2035 today (Oct. 6), making it a perfect time to see the Red Planet with your own eyes. On average, the distance between Mars and Earth is about 140 million miles (225 million kilometres). Here, they can be 250 million miles (401 million km) apart according to the New York Times (opens in new tab). With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. Here are the distances between Earth and the Sun, Mercury, Venus, the Moon, Jupiter, Saturn, Uranus, Neptune, and Pluto. Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): The fastest spacecraft is NASA's Parker Solar Probe, as it keeps breaking its own speed records as it moves closer to the sun. This dust gets kicked up into the atmosphere and from a distance makes the planet appear mostly red. 1.639 times that of Earth. When Earth and Mars are at their theoretically closest point of 54.6 million km, it would take a signal from Earth about 3 minutes to make the journey, and then another 3 minutes for the. Students will need a string 4.5 meters long. The farthest distance between the Sun and Mars as the Red Planet travels in its orbit around the Sun. Mars orbit, opposition and viewing opportunities. Photon propulsion would rely on a powerful laser to accelerate spacecraft to velocities approaching the speed of light.

Sending humans to Mars, however, is a much larger challenge than putting a rover on the Martian surface. Earth Sciences questions and answers; 1) There are 360 in a circle. Nowadays, with several spacecraft orbiting or roaming along the surface of the Red Planet, scientists can use the speed of light to determine how far away Mars is from Earth, by measuring the time it takes for signals to reach Martian spacecraft, according to Universe Today (opens in new tab). From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 astronomical units away from the Sun. The enormity of the distances we talk about in space can be hard to imagine, even with something as relatively close and familiar as Mars. Every 15 to 17 years we witness very close Mars oppositions when Earth passes between Mars and the sun during Mars' perihelion (closest point to the sun). Step 1 of 4. New York, Mars is about half the size of Earth, and like its fellow terrestrial planets, it has a central core, a rocky mantle, and a solid crust. Have groups use the Planet Size Comparison interactive to find and record data on planet diameters and ratios. So, in 2018, Mars should be even closer to the Earth than it is now. So, there's no answer, but the first steps are being taken. How Do We Learn About An Alien Planets Size And Atmosphere? Both planets are in orbit around the sun and a single year for each planet (one complete orbit around the sun) takes a different amount of time. According to NASA Goddard Space Flight Center's website, the ideal lineup for a launch to Mars would get you to the planet in roughly nine months. And theoretically at this point, Mars and Earth will be only 54.6 million kilometers from each other. AsSpace.comexplains, the closest the two planets could theoretically get is 33.9 million miles. In fact, that process has already started. If you're looking for a telescope or binoculars to observe Mars, check our guide for the best binoculars deals and the best telescope deals now. Since Mars and Earth both orbit the Sun but at different distance, with different eccentricities, and with different orbital velocities the distance between then is constantly changing. The Astronomical units (AU) column is the average distance between Earth and the Sun and is the most common way for scientists to measure distance in our Solar System. They start at Earths orbit, and then raise their orbit until they intersect the orbit of Mars; right when Mars is at that point. Planets all orbit the sun at different velocities, so they rarely form a straight line from the sun. This lists the logos of programs or partners of, National Geographic Video: Solar System 101, Nat Geo Movies: Wildest Weather in the Solar System, locations of planets in relation to the sun and one another, relative sizes of planets, including Earth, any conclusions they can draw about the locations of the asteroid belt and Kuiper belt, calculate and model planetary distances by converting astronomical units (AU), analyze relative planetary sizes and distances using a kinesthetic model and data, Tech Setup: 1 computer per small group, Projector, Speakers. This would put the planets only 33.9 million miles (54.6 million kilometers) apart. Both Earth and Mars are following elliptical orbits around the Sun, like two cars travelling at different speeds on two different racetracks. Mars is the fourth planet from the sun, and the second closest to Earth (Venus is the closest). 08, 2014 92.4 million km (57.4 million miles), May. According to a NASA statement (opens in new tab), when the Parker Solar Probe comes within 4 million miles (6.2 million kilometers) of the solar surface in December 2024, the spacecraft's speed will top 430,000 miles per hour!

But one recent study suggests that around 3.2 billion years ago - just as the tectonic plates were starting to move around and . Ask students to describe what they notice about planetary distances from the model. Deimos is about half as big as Phobos and orbits two and a half times farther away from Mars. The temperature on Mars can be as high as 70 degrees Fahrenheit (20 degrees Celsius) or as low as about -225 degrees Fahrenheit (-153 degrees Celsius). 1996 - 2023 National Geographic Society. NASA's Parker Solar Probe is currently the fastest spacecraft ever launched. . Ten sample tubes, capturing an amazing variety of Martian geology, have been deposited on Mars surface so they could be studied on Earth in the future. As a result, there are long- and short-distance calculations between the two planets, with an average distance of 140 million miles (225 . Earth and the Moon appear closer than they actually are in this image because the observation was planned for a time at which the Moon was almost directly behind Earth, from Mars' point of view, to see the Earth-facing side of the Moon. Instead, spacecraft launch towards the point that Mars is going to be in the future. Nearly all comets orbit the Sun in same direction and roughly the same plane. The average distance between Earth and Mars the two planets is 140 million miles (225 million km). Ask students to report back to the class with what they observed. Mars has no global magnetic field today, but areas of the Martian crust in the southern hemisphere are highly magnetized, indicating traces of a magnetic field from 4 billion years ago.. The average distance between Mars and the sun is 142 million miles (228 million kilometers).

The distance between Mars and Earth will vary greatly depending on where each planet is in its orbit. (100 kilograms) robotic spacecraft to Mars in only three days, he said. The answer depends on several factors, ranging from the position of the planets to the technology that would propel you there. To most people (myself included) those are just numbers. Interestingly, while Mars is about half the diameter of Earth, its surface has nearly the same area as Earths dry land. Have groups create models of relative planetary distances.Divide students into groups of 9, 10 or 11, depending on class size. NASA Mars lander felt the ground shake during the impact while cameras aboard the Mars Reconnaissance Orbiter spotted the yawning new crater from space. That's why, depending on budgets, you'll often see that Mars missions launch about every two years: Missed seeing the latest Mars Close Approach? .video_wrapper {height:450px !important;width:100%} area of the solar system between the orbits of Mars and Jupiter filled with asteroids. Occasionally, winds on Mars are strong enough to create dust storms that cover much of the planet. But on average, Mars is about 225 million km/140 million miles from Earth. Its dry, rocky, and bitter cold. This is another similarity with Earth, which has an axial tilt of 23.4 degrees. Learn facts about the solar system's genesis, plus its planets, moons, and asteroids.

MAVEN returned to normal science and relay operations on May 28, 2022, after recovering from an extended safe mode event. The first person to ever calculate the distance to Mars was the astronomer Giovanni Cassini, famous for his observations of Saturn. Since Mars and Earth are at their closest, it's generally the best time to go to Mars. This time of better Mars viewing opportunities can coincide with opposition, when Mars is directly on the opposite side of Earth from the Sun. [7] Find out how the mission teams cope! The numbers also assume that the two planets remain at a constant distance; that is, when a probe is launched from Earth while the two planets are at the closest approach, Mars would remain the same distance away over the 39 days it took the probe to travel. NASA'sArtemis program is working on making this happen right now. However, they have elliptical (egg-shaped) paths. Display the NASA illustration: How Big is the Sun? Like Earth, Mars has distinct seasons, but they last longer than seasons here on Earth since Mars takes longer to orbit the Sun (because it's farther away). Mars: 249,232,432 kilometers 2.49232 x 10 8 km or . In the above number there are significant digits before the decimal point. The outer planets include Jupiter, Saturn, Uranus, and Neptune.

As NASA notes in the handy diagrams above, Mars is 4,220 miles in diameter, which pales in comparison to Earth's 7,926 miles. Ask: Why do you think scientists find it helpful to use astronomical units? The average distance between Earth and Mars is 140 million miles (225 million km). Relative size means how big the planets are when compared to each other and the sun. The website quotes physics professor Craig C. Patten (opens in new tab), of the University of California, San Diego: "It takes the Earth one year to orbit the sun and it takes Mars about 1.9 years (say 2 years for easy calculation) to orbit the sun. Their numbers factor in not only distance but also fuel efficiency. How did it form in the Milky Way galaxy? That's about the exact same distance it'll be from Earth when the planets have another close approach in 2022. The main asteroid belt lies between the orbits of Mars and Jupiter, separating the inner and outer planets. Mars' sparse atmosphere doesn't offer much protection from impacts by such objects as meteorites, asteroids, and comets. Many missions have taken advantage of the close distance to Mars which is why you'll often see Mars missions launch (if budget allows) every two years. The Mars landers seismometer has picked up vibrations from four separate impacts in the past two years. This makes it extremely difficult to create an exact scale of our solar system, so this activity will focus on the distance comparison. The Red Planet makes for an interesting observing target in the night sky. If needed, allow one student from each group to put an object in their place and walk around their groups model to make observations.6. Mars and Earth are farthest apart when they are both at aphelion and on opposite sides of the sun. large, spherical celestial body that regularly rotates around a star. Ask: Which planet is the smallest? Both are close to essential to allow a planet to retain a human breathable atmosphere. How far away is Mars? Distribute one copy of the worksheet Planetary Size Comparison to each group. For this reason, to calculate the distance, we use the average to measure how far planets are from one another. NASA will host a briefing at 11:30 a.m. EDT on Sept. 15, to provide highlights from the first year and a half of the Perseverance rovers mission. Theres no question Mars is bright and close, you can see it with your own eyes. copy of an object that is larger or smaller than the actual object, but maintaining the same proportions. Northern winter/southern summer is 154 sols, and northern summer/southern winter is 178 sols. But the distance between Earth and Mars is constantly changing as they travel around the sun. When Earth and Mars reach their closest point, this is known as opposition. Make sure students understand that the distances between the planets are very large compared to the sizes of each planet. In theory, the closest Mars and Earth would getis when Mars reaches its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). The distance to Mars from Earth is not that simple. The Perseverance rover is carrying potential spacesuit material for astronauts who make the journey in order to test its resilience in the Martian atmosphere. At its closest approach to Earth in 2020, Mars was about 38.6 million miles (62.07. The 10 sample tubes being dropped on Mars surface so they can be studied on Earth in the future carry an amazing diversity of Red Planet geology. Engineers must calculate the ideal orbits for sending a spacecraft from Earth to Mars. So, the gravitational force exhibited by Mars is not experienced by us due to the large distance. Related: What is the temperature on Mars? A large canyon system called Valles Marineris is long enough to stretch from California to New York more than 3,000 miles (4,800 kilometers). We take a look at how long a trip to the Red Planet would take using available technology and explore some of the factors that would affect your travel time. Explore NASA's lunar exploration plans with their Moon to Mars overview (opens in new tab). When the solar system settled into its current layout about 4.5 billion years ago, Mars formed when gravity pulled swirling gas and dust in to become the fourth planet from the Sun. Moore Boeck, A 3D model of Mars, a terrestrial planet. However, that doesn't happen very often. Its dust season and winter on Mars, meaning theres more dust in the air and less sunlight to help recharge Ingenuitys batteries. length between two points relayed in non-physical units such as time. The farthest apart they can be is about 401 million km, or 401 billion meters. The mission has concluded that the solar-powered lander has run out of energy after more than four years on the Red Planet. In order to have the supplies needed to set up facilities on the planet, multiple trips to Mars will be required. The Nine Planets has been online since 1994 and was one of the first multimedia websites that appeared on the World Wide Web. Code of Ethics| 30, carrying the Perseverance rover. Finally, if youd like to learn more about Mars in general, we have done several podcast episodes about Mars at Astronomy Cast. When Jupiter and Earth are on the same line from the sun, the distance is approximately 600,000,000 kilometers. (A rocket you made up or on the path which NASA has sent rovers?) Take an interactive tour of the solar system, or browse the site to find fascinating information, facts, and data about our planets, the solar system, and beyond. Added 9 minutes 8 seconds ago|3/3/2023 7:27:41 AM Close Approach is when Mars and Earth come nearest to each other in their orbits around the sun. The closest distance between Earth and Mars is approximately 3.39x107 miles. Neither Earth or Mars' orbit is perfectly circular, so the distance between the two is constantly changing. The answer to that question changes from moment to moment because Earth and Mars are orbiting the Sun. How big is Mars compared to Earth? Here is a list of how long it took several historical missions to reach the red planet (either orbiting or landing on the surface). Spacecraft dont launch directly at Mars; that would use up too much fuel. Use the provided answer key to check groups work. For information on user permissions, please read our Terms of Service.

And theoretically at this point, Mars and Earth will be only 54.6 million kilometers from each other. AsSpace.comexplains, the closest the two planets could theoretically get is 33.9 million miles. In fact, that process has already started. If you're looking for a telescope or binoculars to observe Mars, check our guide for the best binoculars deals and the best telescope deals now. Since Mars and Earth both orbit the Sun but at different distance, with different eccentricities, and with different orbital velocities the distance between then is constantly changing. The Astronomical units (AU) column is the average distance between Earth and the Sun and is the most common way for scientists to measure distance in our Solar System. They start at Earths orbit, and then raise their orbit until they intersect the orbit of Mars; right when Mars is at that point. Planets all orbit the sun at different velocities, so they rarely form a straight line from the sun. This lists the logos of programs or partners of, National Geographic Video: Solar System 101, Nat Geo Movies: Wildest Weather in the Solar System, locations of planets in relation to the sun and one another, relative sizes of planets, including Earth, any conclusions they can draw about the locations of the asteroid belt and Kuiper belt, calculate and model planetary distances by converting astronomical units (AU), analyze relative planetary sizes and distances using a kinesthetic model and data, Tech Setup: 1 computer per small group, Projector, Speakers. This would put the planets only 33.9 million miles (54.6 million kilometers) apart. Both Earth and Mars are following elliptical orbits around the Sun, like two cars travelling at different speeds on two different racetracks. Mars is the fourth planet from the sun, and the second closest to Earth (Venus is the closest). 08, 2014 92.4 million km (57.4 million miles), May. According to a NASA statement (opens in new tab), when the Parker Solar Probe comes within 4 million miles (6.2 million kilometers) of the solar surface in December 2024, the spacecraft's speed will top 430,000 miles per hour! In 2020, The UAE's Hope mission launched from Japan's Tanegashima Space Center on Jul. xmlns:xsl='http://www.w3.org/1999/XSL/Transform'">. But one recent study suggests that around 3.2 billion years ago - just as the tectonic plates were starting to move around and . Ask students to describe what they notice about planetary distances from the model. Deimos is about half as big as Phobos and orbits two and a half times farther away from Mars. The temperature on Mars can be as high as 70 degrees Fahrenheit (20 degrees Celsius) or as low as about -225 degrees Fahrenheit (-153 degrees Celsius). 1996 - 2023 National Geographic Society. NASA's Parker Solar Probe is currently the fastest spacecraft ever launched. . Ten sample tubes, capturing an amazing variety of Martian geology, have been deposited on Mars surface so they could be studied on Earth in the future. As a result, there are long- and short-distance calculations between the two planets, with an average distance of 140 million miles (225 . Earth and the Moon appear closer than they actually are in this image because the observation was planned for a time at which the Moon was almost directly behind Earth, from Mars' point of view, to see the Earth-facing side of the Moon. Instead, spacecraft launch towards the point that Mars is going to be in the future. Nearly all comets orbit the Sun in same direction and roughly the same plane. The average distance between Earth and Mars the two planets is 140 million miles (225 million km). Ask students to report back to the class with what they observed. Mars has no global magnetic field today, but areas of the Martian crust in the southern hemisphere are highly magnetized, indicating traces of a magnetic field from 4 billion years ago.. The average distance between Mars and the sun is 142 million miles (228 million kilometers). National Geographic Headquarters The average distance between Mars and the sun is 142 million miles (228 million kilometers). It's three times taller than Earth's Mt. The distance between Mars and Earth will vary greatly depending on where each planet is in its orbit. (100 kilograms) robotic spacecraft to Mars in only three days, he said. The answer depends on several factors, ranging from the position of the planets to the technology that would propel you there. To most people (myself included) those are just numbers. Interestingly, while Mars is about half the diameter of Earth, its surface has nearly the same area as Earths dry land. Have groups create models of relative planetary distances.Divide students into groups of 9, 10 or 11, depending on class size. NASA Mars lander felt the ground shake during the impact while cameras aboard the Mars Reconnaissance Orbiter spotted the yawning new crater from space. That's why, depending on budgets, you'll often see that Mars missions launch about every two years: Missed seeing the latest Mars Close Approach? .video_wrapper {height:450px !important;width:100%} area of the solar system between the orbits of Mars and Jupiter filled with asteroids. Occasionally, winds on Mars are strong enough to create dust storms that cover much of the planet. But on average, Mars is about 225 million km/140 million miles from Earth. Its dry, rocky, and bitter cold. This is another similarity with Earth, which has an axial tilt of 23.4 degrees. Learn facts about the solar system's genesis, plus its planets, moons, and asteroids.

MAVEN returned to normal science and relay operations on May 28, 2022, after recovering from an extended safe mode event. The first person to ever calculate the distance to Mars was the astronomer Giovanni Cassini, famous for his observations of Saturn. Since Mars and Earth are at their closest, it's generally the best time to go to Mars. This time of better Mars viewing opportunities can coincide with opposition, when Mars is directly on the opposite side of Earth from the Sun. [7] Find out how the mission teams cope! The numbers also assume that the two planets remain at a constant distance; that is, when a probe is launched from Earth while the two planets are at the closest approach, Mars would remain the same distance away over the 39 days it took the probe to travel. NASA'sArtemis program is working on making this happen right now. However, they have elliptical (egg-shaped) paths. Display the NASA illustration: How Big is the Sun? Like Earth, Mars has distinct seasons, but they last longer than seasons here on Earth since Mars takes longer to orbit the Sun (because it's farther away). Mars: 249,232,432 kilometers 2.49232 x 10 8 km or . In the above number there are significant digits before the decimal point. The outer planets include Jupiter, Saturn, Uranus, and Neptune. This allows them to measure the distance to planets, like Mars, with incredible accuracy.

To compare the planets Earth and Mars and to demonstrate the distance between the two planets. You cannot download interactives. As NASA notes in the handy diagrams above, Mars is 4,220 miles in diameter, which pales in comparison to Earth's 7,926 miles. Ask: Why do you think scientists find it helpful to use astronomical units? The average distance between Earth and Mars is 140 million miles (225 million km). Relative size means how big the planets are when compared to each other and the sun. The website quotes physics professor Craig C. Patten (opens in new tab), of the University of California, San Diego: "It takes the Earth one year to orbit the sun and it takes Mars about 1.9 years (say 2 years for easy calculation) to orbit the sun. Their numbers factor in not only distance but also fuel efficiency. How did it form in the Milky Way galaxy? That's about the exact same distance it'll be from Earth when the planets have another close approach in 2022. The main asteroid belt lies between the orbits of Mars and Jupiter, separating the inner and outer planets. Mars' sparse atmosphere doesn't offer much protection from impacts by such objects as meteorites, asteroids, and comets. Many missions have taken advantage of the close distance to Mars which is why you'll often see Mars missions launch (if budget allows) every two years. The Mars landers seismometer has picked up vibrations from four separate impacts in the past two years. This makes it extremely difficult to create an exact scale of our solar system, so this activity will focus on the distance comparison. The Red Planet makes for an interesting observing target in the night sky. If needed, allow one student from each group to put an object in their place and walk around their groups model to make observations.6. Mars and Earth are farthest apart when they are both at aphelion and on opposite sides of the sun. large, spherical celestial body that regularly rotates around a star. Ask: Which planet is the smallest? Both are close to essential to allow a planet to retain a human breathable atmosphere. How far away is Mars? Distribute one copy of the worksheet Planetary Size Comparison to each group. For this reason, to calculate the distance, we use the average to measure how far planets are from one another. NASA will host a briefing at 11:30 a.m. EDT on Sept. 15, to provide highlights from the first year and a half of the Perseverance rovers mission. Theres no question Mars is bright and close, you can see it with your own eyes. copy of an object that is larger or smaller than the actual object, but maintaining the same proportions. Northern winter/southern summer is 154 sols, and northern summer/southern winter is 178 sols. But the distance between Earth and Mars is constantly changing as they travel around the sun. When Earth and Mars reach their closest point, this is known as opposition. Make sure students understand that the distances between the planets are very large compared to the sizes of each planet. In theory, the closest Mars and Earth would getis when Mars reaches its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). The distance to Mars from Earth is not that simple. The Perseverance rover is carrying potential spacesuit material for astronauts who make the journey in order to test its resilience in the Martian atmosphere. At its closest approach to Earth in 2020, Mars was about 38.6 million miles (62.07. The 10 sample tubes being dropped on Mars surface so they can be studied on Earth in the future carry an amazing diversity of Red Planet geology. Engineers must calculate the ideal orbits for sending a spacecraft from Earth to Mars. So, the gravitational force exhibited by Mars is not experienced by us due to the large distance. Related: What is the temperature on Mars? A large canyon system called Valles Marineris is long enough to stretch from California to New York more than 3,000 miles (4,800 kilometers). We take a look at how long a trip to the Red Planet would take using available technology and explore some of the factors that would affect your travel time. Explore NASA's lunar exploration plans with their Moon to Mars overview (opens in new tab). When the solar system settled into its current layout about 4.5 billion years ago, Mars formed when gravity pulled swirling gas and dust in to become the fourth planet from the Sun. Moore Boeck, A 3D model of Mars, a terrestrial planet. However, that doesn't happen very often. Its dust season and winter on Mars, meaning theres more dust in the air and less sunlight to help recharge Ingenuitys batteries. length between two points relayed in non-physical units such as time. The farthest apart they can be is about 401 million km, or 401 billion meters. The mission has concluded that the solar-powered lander has run out of energy after more than four years on the Red Planet. In order to have the supplies needed to set up facilities on the planet, multiple trips to Mars will be required. The Nine Planets has been online since 1994 and was one of the first multimedia websites that appeared on the World Wide Web. Code of Ethics| 30, carrying the Perseverance rover. Finally, if youd like to learn more about Mars in general, we have done several podcast episodes about Mars at Astronomy Cast. When Jupiter and Earth are on the same line from the sun, the distance is approximately 600,000,000 kilometers. (A rocket you made up or on the path which NASA has sent rovers?) Take an interactive tour of the solar system, or browse the site to find fascinating information, facts, and data about our planets, the solar system, and beyond. Added 9 minutes 8 seconds ago|3/3/2023 7:27:41 AM Close Approach is when Mars and Earth come nearest to each other in their orbits around the sun. The closest distance between Earth and Mars is approximately 3.39x107 miles. Neither Earth or Mars' orbit is perfectly circular, so the distance between the two is constantly changing. The answer to that question changes from moment to moment because Earth and Mars are orbiting the Sun. How big is Mars compared to Earth? Here is a list of how long it took several historical missions to reach the red planet (either orbiting or landing on the surface). Spacecraft dont launch directly at Mars; that would use up too much fuel. Use the provided answer key to check groups work. For information on user permissions, please read our Terms of Service. Rings _______________ What is the farthest distance between Earth and Mars? 2 See answers Advertisement skyluke89 I guess the problem is asking for the distance between Earth and Mars in Astronomical Units (AU).

Anna Mika, M.S. 03, 2012 100.7 million km (62.6 million miles), Apr. javascript is enabled. To most of us, dust is an annoyance. That's 204 days, which is less than the253 daysit took curiosity to get to Mars in 2012. On the opposite end of the scale, Mars and Earth can be 401 million km apart (249 million miles) when they are in opposition and both are at aphelion. If a media asset is downloadable, a download button appears in the corner of the media viewer. NASA has extended the planetary science missions of eight of its spacecraft due to their scientific productivity and potential to deepen our knowledge. So, the Earth Mars distance is changing from minute to minute. Its the time that Mars appears as a bright red star of the sky; one of the brightest objects, rivaling the brightness of Venus or Jupiter. The Moon is 384,400 kilometers (km) (240,250 miles) from the Earth. the sun and the planets, asteroids, comets, and other bodies that orbit around it.
