Named after the roman god of war because of its dusty red appearance, Mars is known as The Red Planet. Along with Mercury, Venus, and Earth, it is one of the four terrestrial planets of the inner Solar System.

The martian moons-Phobos and Deimos are small sattelites with a lower density than Mars. They may be asteroid captured by the Martian gravity.

Olympus Mons is the largest volcano in the Solar System, and Valles Marineris a vast canyon system.
