Simply go outside and look up and, depending on your local weather and lighting conditions, you should be able to see Mars. Pluto, which used to be considered the ninth planet, is now classified as a dwarf planet and part of the Kuiper Belt. This would bring the two planets within 33.9 million miles (54.6 million kilometers) of each other but this has not yet happened in recorded history according to NASA (opens in new tab). When the planets are as far away from each other as possible, they could be as many as 250 million miles apart. After such storms, it can be months before all of the dust settles. Remind students that Pluto is no longer considered a planet in our solar system; it was downgraded to the status of dwarf planet in 2006. They will best know the preferred format. Like throwing a dart at a moving target, they must calculate where the planet will be when the spacecraft arrives, not where it is when it leaves Earth. Find out how the mission teams cope! And although they get close and far apart, those points depend on where the planets are on their particular orbits. A year on Mars lasts 669.6 sols, which is the same as 687 Earth days. The mission has concluded that the solar-powered lander has run out of energy after more than four years on the Red Planet. Related: How long does it take to get to Mars? If Earth and Mars had perfectly circular orbits, their minimum distance would always be the same. They start at Earths orbit, and then raise their orbit until they intersect the orbit of Mars; right when Mars is at that point. Its dry, rocky, and bitter cold. The minimum distance from the Earth to Mars is about 54.6 million kilometers. . According to NASA, the two will not be that close again until the year 2237. 4.
