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.
Moons could come and go over the billions of years of the Earthâs history. For example, Mars has two Moons, but not for long. Phobos, the larger moon, is spiraling inward and expected to crash into the planet within the next 10 million years. And so, in the future, Mars will only have a single Moon, Deimos. Itâs also possible that the Earth might capture a Moon in the future.
