How far away is Mars? The exact answer varies, of course, as both it and our planet are constantly moving along their own orbits around the Sun. But on average, Mars is about 225 million km/140 million miles from Earth. Give or take a few. To most people (myself included) those are just numbers. Big numbers â and really not even all that big in an astronomical sense.
Mars is the fourth planet from the Sun and orbits the Sun at an average distance of approximately 141 million miles (225 million km). Mars rotates on its axis, completing one revolution every 24.6 hours. The axis of Mars is tilted at 25 degrees and 12 minutes relative to its orbital plane about the Sun. This produces seasons on the surface of Mars, similar to the seasons on Earth.
