What did Deimos look like?

Deimos, the smaller moon of Mars, is a small and lumpy object with a heavily cratered surface, featuring craters generally smaller than 1.6 miles (2.5 kilometers) in diameter, and it lacks the grooves and ridges seen on its counterpart, Phobos. The appearance of Deimos is characterized by a dark, reddish color, with a smooth surface due to a blanket of fragmental rock or regolith, except for the most recent impact craters.
