is a
Lunar Impact Crater that is located in the northern
Hemisphere on the
Far Side of the
Moon . It lies to the southwest of the larger
Robertson Crater , and to the east of
Ohm Crater .
The outer rim of Alter crater has been degraded by subsequent erosion, most notably at the northern and southern extremes. There is a small crater lying across the south-southeast rim. A cleft runs across the floor from the southern rim toward the north-northeast.
Ray material cross the crater floor from the east, forming a pair of faint bands.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Alter crater.
