Rayet (Moon)

Named after Georges-Antoine-Pons Rayet - French astronomer (1839-1906).

Rayet is a small lunar impact crater that lies on the far side , past the northeast limb. It lies to the southwest of the larger crater Millikan, and east of the comparably sized Petrie. This crater is roughly circular in shape, with a sharp edge and featureless inner walls that slope downward to the nearly level interior floor. The diameter of the floor is roughly two-thirds that of the crater. (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.
