is a small
Lunar Impact Crater that lies in the rugged region between the
Montes Apenninus range to the west and the
Montes Haemus in the east. It is located to the south-southeast of
Aratus Crater , a slightly larger formation. Further to the west is
Conon Crater , near the flanks of the Montes Apeninnus. Galen was previously designated 'Aratus A' before being given a name by the
IAU .
This is a circular crater with a bowl-shaped interior and a sharp rim that has not undergone significant erosion. The small interior floor has a lower
Albedo than the surrounding walls.
