Eponym Sosigenes of Alexandria

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

To the east on the mare is a 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[edit]

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