Lundmark (Moon)

Named after Knut Emil Lundmark - Swedish astronomer (1889-1958).

Lundmark is an eroded crater on the far side. It lies to the southwest of the Mare Ingenii, one of the rare mare areas on the far side. Nearly attached to the southwestern outer rim is the crater Koch, and located to the northwest is the flooded Jules Verne. It is a heavily worn and damaged crater formation that is marked by a number of smaller craters along the sides and interior. (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.
