Pitiscus (Moon)

Named after Bartholemaeus Pitiscus - German mathematician (1561-1613).

Pitiscus is a lunar impact crater that lies in the southern part 's near side, just to the northwest of the larger crater Hommel. The crater is worn, but still forms a prominent feature upon the surface. The rim is roughly circular, but appears oval from the Earth due to foreshortening. There is an outward bulge to the south-southeast where the interior has slumped. (wikipedia entry)

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.
