Mars is the fourth planet from the sun. Mars has  two Moons, Phobos and Deimos. They were both discovered in 1877, by Asaph Hall at the Naval Observatory in Washington DC. Phobos is the larger one of Marsâ moons, and it orbits closer to the surface of Mars than Deimos does.
Virtually every planet in the solar system has moons. Earth has the moon, Mars has Phobos and Deimos, and Jupiter and Saturn have 67 and 62 officially named moons, respectively. Heck, even the recently-demoted dwarf planet Pluto has five confirmed moons â Charon, Nix, Hydra, Kerberos and Styx.
