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.
In Latin, the names of the moons mean panic and fear, respectively. Unlike the Earthâs moon both of the moons on Mars are not round. They both have an irregular shape and are much smaller compared to the Earthâs moon. The sizes of the moons include 7.8 miles across for Deimos and 13.8 miles across for Phobos. Both of these moons are comprised of iron and rock, and they are covered with craters. The History of the Moons on Mars. Scientists do not have a definitive answer concerning how Mars acquired both of these moons. It is largely believed that the gravity of Mars captured them at some point, but before this, they were two asteroids. Both of these moons were discovered by scientists in 1877.
