Does Mars have any moons?

Yes, Mars has two small moons named Phobos and Deimos. Their names mean fear and panic in Latin. Phobos and Deimos are not round like our Moon. They are much smaller and have irregular shapes. Phobos is 13.8 miles (22.2 km) across and Deimos is only 7.8 miles (12.6 km) across. Both moons are covered with craters and are made of rock and iron. It is possible that Phobos and Deimos were two asteroids which were captured by the gravity of Mars.
