Franck (Moon)

Named after James Franck - German physicist; Nobel laureate (1882-1964).

Franck is a small lunar impact crater that lies near the north end of Sinus Amoris, a bay on the northern part of Mare Tranquillitatis. The crater lies just to the southeast of Brewster, and farther to the south of Römer. (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.
