This is a relatively young formation with features that have not received a significant amount of wear or erosion from subsequent impacts. The edge of the rim is sharply defined, and the inner wall is
terraced along the northwestern side. The interior floor is relatively level, with a double-peak formation at the midpoint.
Störmer P, a satellite crater, is attached to the exterior of the rim of Störmer along the southwest side.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Störmer.
