Franz (Moon)

Named after Julius Heinrich Franz - German astronomer (1847-1913).

Franz is a small lunar crater identified during the Apollo mission in August 1971 and located along the eastern edge of the Sinus Amoris, a bay that forms a northern extension to the Mare Tranquillitatis. It lies to the southwest of the prominent crater Macrobius. To the north is the smaller Carmichael, and to the northwest is the diminutive Theophrastus. The rim of this crater has been eroded due to subsequent impacts, although it retains a generally circular form. (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.
