Dufay (Moon)

Named after Jean Claude Barthélemy Dufay - French astronomer (1896-1967).

Dufay is a lunar crater on the far side. It lies about one crater diameter to the east of the large walled plain Mandel'shtam. To the northwest is the crater Papaleksi and to the east is Valier. The rim of this crater is heavily worn by impacts, and several small craterlets lie along the southern edge. (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.
