Eponym Sosigenes
Sosigenes is a lunar impact crater on the west edge of Mare Tranquillitatis. It lies to the east of the large Julius Caesar walled-plain. The crater rim has a high albedo, making it relatively bright. It has a small central rise at the mid-point of the floor.

To the east on the mare is formation of parallel rilles designated the Rimae Sosignes. These follow a course to the north, and have a length of about 150 kilometers. The small, bowl-shaped crater 'Sosignes A' lies across one of these rilles.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Sosigenes crater.
