Mars's moons, Phobos and Deimos, share many characteristics with two types of asteroids common in the belt: C- and D-type asteroids.
Moreover, by the looks of Phobos and Deimos, we can easily assume that they are both captured objects from the Asteroid Belt, that maybe there was a collision...

Large Impact Theory
The Large Impact Theory brings upon the idea that Mars has suffered a large collision. Just like how the Earth's moon is the result of an immpact between our infant planet and a planetisimal named Theia.
With this theory, astronomers suggest that the composition of Phobos and Deimos may hav...

The reason Mars looks reddish is due to oxidization—or rusting—of iron in the rocks, regolith (Martian “soil”), and dust of Mars. This dust gets kicked up into the atmosphere and from a distance makes t...
