Satellite Feature of Geiger

Named after Johannes Hans Wilhelm Geiger - German physicist (1882-1945).

Geiger is a lunar crater on the far side. It lies to the southwest of the much larger walled plain Keeler, and slightly farther to the northeast of the huge walled plain Gagarin. To the south is the crater Cyrano. This is a not-quite symmetrical crater formation with small outward bulges along the north and northeast. (wikipedia entry)
