It is colder inside some craters near the lunar poles than it is on the surface of Pluto (25K, or -415F). During opposition, Mars and the sun are on directly opposite sides of Earth. Those different orbital speeds mean that the distance between any two planets is always changing. But these tiny particles that float about and settle on surfaces play an important role across the solar system. The main asteroid belt lies between the orbits of Mars and Jupiter, separating the inner and outer planets. 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. 2 See answers Advertisement skyluke89 I guess the problem is asking for the distance between Earth and Mars in Astronomical Units (AU). Look up! During Mars oppositions, from Earth, we can see Mars rise in the east as the sun sets in the west, with the Red Planet being visible in our skies all night long. How far away is Mars? The rover found that Jezero Craters floor is made up of volcanic rocks that have interacted with water. "There are recent advances which take this from science fiction to science reality," Lubin said at the 2015 NASA Innovative Advanced Concepts (NIAC) fall symposium.
