Mars hosts many enormous extinct volcanoes (the tallest is Olympus Mons, 21.9 km or 13.6 mi tall) and one of the largest canyons in the Solar System (Valles Marineris, 4,000 km or 2,500 mi long). Geologically, the planet is fairly active with marsquakes trembling underneath the ground, dust devils sweeping across the landscape, and cirrus clouds.
Earth orbits the sun in a slightly uneven circle, keeping an average distance of 93 million miles. Mars’s orbit is much more elliptical—with an aphelion, or furthest remove from the sun, of ...
