Sternfeld (Moon)

Named after Ari Abramovich Sternfeld - Soviet space scientist (1905-1980).

Sternfeld is a lunar impact crater on the far side. It lies to the south-southwest of the crater Paschen, and to the east-southeast of the smaller Lodygin. This is a heavily eroded crater formation with an outer rim that has been considerably worn by subsequent impacts. As a result, the outer rim is irregular and poorly defined. (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.
