. The formation is nearly circular, with a sharp-edged rim and little appearance of erosion. There are slight outward bulges in the rim to the north and northeast, but otherwise the formation is relatively symmetrical.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Galle.
