   Is Mars a sphere?

   • Despite appearances, Mars is not a sphere. Because the planet rotates on its axis (every 24.6 hours), it bulges at the equator (as do Earth and other planets). At its equator, Mars has a diameter of 4,222 miles (6,794 km), but from pole to pole, the diameter is 4,196 miles (6,752 km). Mars’ radius is, of course, half of planet’s diameter.

   What does Mars look like?

   • Mars – the fourth planet from the Sun – is a dusty, cold, desert world with a very thin atmosphere. This dynamic planet has seasons, polar ice caps, extinct volcanoes, canyons and weather. Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to roam the alien landscape.
