Named after Agrippa - Greek astronomer (unkn-fl. A.D. 92).
Agrippa is located to the north of the crater Godin, and the irregular Tempel lies just to the east. To the north and northeast, the rille designated Rima Ariadaeus follows a course to the east-southeast, reaching the western edge of Mare Tranquillitatis. The rim has an unusual shape, resembling the form of a shield with a rounded southern rim and a more angular northern half. (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.
