Satelite Mars

Mars has two known moons, Phobos and Deimos,which are thought to be captured asteroids. Both satellites were discovered in 1877 by Asaph Hall and are named after the characters Phobos (panic/fear) and Deimos (terror/dread) who, in Greek mythology, accompanied their father Ares, god of war, into battle. Ares was known as Mars to theRomans. It is possible that Mars may have moons smaller than 50 - 100 meters and a dust ring between Phobos and Deimos may be present but none have been discovered.
