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.
Mars has two known moons, Phobos and Deimos (fear and dread, after attendants of Ares, the Greek god of war, equivalent to the Roman Mars). Searches for more satellites have been unsuccessful, putting the maximum radius of any other satellites at 90 m (100 yd).
