Similarly, an early moon of Mars could have been impacted by a large object, leaving Phobos and Deimos as the only remaining bits. The diameter of the Phobos is around 22.23 km (13.8 mi), whereas the diameter of Deimos is around 12.56 km (7.8 mi). Of the four rocky, terrestrial planets, only Mars has more than one moon.

Hall discovered Deimos on Aug. 12 and Phobos on Aug. 18. Phobos and Deimos may someday be useful as “space stations” from which to study Mars or as intermediate stops to and from the Martian surface; especially if the presence of ice is confirmed. Due to the low mass and low gravity, it can not sustain the atmosphere. Join our Space Forums to keep talking space on the latest missions, night sky and more! MMX will land on the surface of Phobos and collect samples to be returned to Earth in 2029. You will receive a verification email shortly. Mars is named after the Roman god of war, while its moons, Phobos and Deimos, are named after the horses that pulled the chariot of the god himself.

Both are also made up of material that resembles Type I or II carbonaceous chondrites, the substance that makes up asteroids. It is possible that the moons formed like the planet, from debris left over from the creation of Mars. Phobos is slowly spiraling inward at a rate of 6 feet (1.8 meters) every century. Scientists have predicted that in the future, about 30 to 50 million years later it will either collide with Mars or collapse and will create a planetary ring around Mars. Phobos is named after the Greek god Phobos, a son of Ares (Mars) and Aphrodite (Venus) and twin brother of Deimos. "Understanding how Phobos and Deimos formed has been a goal of the planetary science community for many years," David Lawrence, of the Applied Physics Laboratory, said in a statement. Despite the smaller size, it has a crater named Voltaire with an average diameter of around 3 km. Space is part of Future US Inc, an international media group and leading digital publisher.
