Geological Chronicle

Focas is a small lunar impact crater that lies on the far side of the Moon, just past the southwestern limb. The formation spans an official diameter of 22.04 kilometers.

In this location the crater is occasionally brought into view due to libration, but not much detail can be seen because the crater is viewed from the side. It is recorded in the IAU Gazetteer under quadrangle LAC-123.
