To the north-northwest is the smaller crater Cepheus, and in the opposite direction to the southwest is the shallow Berzelius. The inner wall is terraced, and there is a central peak at the midpoint of the floor. A narrow cleft runs to the west-southwest across the floor, passing to the north of the central peak.

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
