The
moons of Mars are
Phobos and
Deimos. Both moons 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 the
Romans. It is possible that Mars may have moons smaller than 50–100 meters and a dust ring between Phobos and Deimos, but none have been discovered.
