Sirsalis B (Moon)

Satellite Feature of Sirsalis

Named after Sersale, Gerolamo Sirsalis - Italian astronomer (1584-1654).

Sirsalis is a young lunar impact crater located near the western lunar limb, to the southwest of the Oceanus Procellarum. The crater lies across a ridge that runs in a north–south direction. It has a sharp edge and a low central peak. The crater overlaps the slightly larger and older Sirsalis A to the west-southwest, and the two form a distinctive feature. (wikipedia entry)
