Apollonius (crater)

Apollonius is a lunar crater located near the eastern limb of the Moon. It lies in the region of uplands to the west of Mare Undarum and northeast of the Sinus Successus on the Mare Fecunditatis. It is southwest of the crater Firmicus, and north of Condon crater.The outer rim of Apollonius is somewhat worn and is overlaid by a pair of small craters (including 'Apollonius E') across the western wall. The nearly flat interior floor has a low albedo and has been covered by lava. It lacks a central peak or notable small craters across the bottom.
