Meton (Moon)

Named after Meton - Greek astronomer (unkn-fl. 432 B.C.).

Meton is a compound formation that consists of several merged crater rings that have been flooded with lava, forming the remnant of a walled plain in the shape of a clover leaf. The crater Barrow is attached to the southwest rim. To the northwest is the crater Scoresby, and to the east are Baillaud and Euctemon. (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.
