Previously unpublished photos of Mars' moon Phobos hint that the mysterious satellite may actually be a trapped comet — or perhaps just a piece of one, along with its twin moon Deimos.

Phobos – the closest of Mars' two moons – is set to get ever closer to the planet, before its final descent, while Deimos will drift ever outwards until it leaves Mars' orbit.

The origin of the martian moons Phobos and Deimos is still an unsolved mystery in planetary research. Both moons will be the targets of the Japanese Martian Moons eXploration (MMX) mission. A ...

The two moons of Mars, Phobos and Deimos, were discovered in 1877 by the American astronomer Asaph Hall using the 26-inch refractor telescope at the U.S. Naval Observatory in Washington D.C.

Of Mars’s two moons, Phobos is slightly larger. Both are irregularly shaped, like potatoes. Phobos is about 27 km across on its longest side, and Deimos is 15 km across.
