What is the distance between the Earth and Mars?

Answer

Mars and Earth both revolve around the sun, so their relative distance fluctuates over time. According to Cornell University, Mars has an average distance from the sun that is 1.5 times that of Earth, so at their closest approach, the two planets are separated by 0.5 astral units.

One astral unit is roughly 150 million kilometers, according to Cornell University, and so the minimum distance to Mars is never less than 75 million kilometers. As the two planets move to opposite sides of the sun, however, that distance increases to a maximum of 2.5 astral units, or 375 million kilometers.
