Mars if the fourth planet from the sun its named after the roman god of war.Mars also has some of the most interesting terrain features of any of the terrestrial planets. These include the largest mountain in the Solar System – Olympus Mons – which rises some 21,229 m (69,649 ft) above the surface, and a giant canyon called Valles Marineris. Valles Marineris is 4000 km (2500 mi) long and reaches depths of up to 7 km (4 mi)!
Mars is less dense than Earth and has a smaller magnetic field, which is indicative of a solid core, rather than a liquid one
Mars’ thin atmosphere has led some astronomers to believe that the surface water that once existed there might have actually taken liquid form, but has since evaporated into space. The planet has two small moons called Phobos and Deimos.
Mars has a very red tint which is due to a mineral called iron oxide which is very common on the planet. Like earth mars has polar ice caps , seasons and the length of our days and years are quite similar.
