Cleostratus J (Moon)

Satellite Feature of Cleostratus

Named after Cleostratus - Greek astronomer (unkn-c. 500 B.C.).

Cleostratus is a lunar crater near the northwest limb. It lies to the northeast of the crater Xenophanes, and west-southwest of the prominent Pythagoras. From the Earth this crater appears highly elongated due to foreshortening. The rim of this crater has become soft-shouldered due to steady impact erosion, and the formation is now just a depression in the surface surrounded by an eroded rise. (wikipedia entry)
