Censorinus (Moon)

Named after Censorinus - Roman astronomer (fl. A.D. 238).

Censorinus is a tiny lunar impact crater located on a rise to the southeast of the Mare Tranquillitatis. To the northeast is the crater Maskelyne. Censorinus is distinguished by an area of high-albedo material surrounding the rim. This makes the feature highly prominent when the Sun is at a high angle, and it is one of the brightest objects on the visible Moon. (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.
