Focas is a small impact crater on the back of Earth's moon , just past the southwestern rim. In this position the crater is occasionally visible from the earth due to the libration . Since you are looking at it from the side, you can hardly make out any details. The circular, isolated crater has an inner floor surface without significant structures or impact marks, with a diameter of about 10 kilometers . Only the symmetrical edge shows slight signs of wear.
The crater lies in the wide valley between the ring-shaped Rook Mountains in the north and the mountain range of the lunar cordilleras in the south. These two mountain ranges enclose the Mare Orientale impact basin as a double ring . Focas is at the southern end of this massive structure, just north of the Montes Cordillera .
The closest craters of importance are Wright and Shaler craters, visible some distance to the east , on the same inner edge of the Cordillera.
