Tags: Crater.
Focas is a small lunar impact crater that lies on the far side of the Moon just past the southwestern limb. 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.The crater is situated in the wide valley between the ring-shaped Montes Rook in the north and Montes Cordillera range in the south. These ranges form a double-ring around the Mare Orientale impact basin.
