Eponym	James Glaisher

Glaisher is a lunar impact crater that is located in the region of terrain that forms the southwest border about Mare Crisium. It lies to the southwest of the lava-flooded Yerkes crater, and west-northwest of the Greaves-Lick crater pair. It is surrounded by a ring of satellite craters of various dimensions, the larger companions generally being arranged to the south of Glaisher.

This crater is circular, with a bowl-shaped interior and a small floor at the mid-point. The crater has not been significantly worn by subsequent impacts. A merged, double-crater formation is attached to its southern rim, consisting of 'Glaisher E' at the northwest end and 'Glaisher G' to the southeast.

[edit] 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 Glaisher crater.
