is a
Lunar Crater that is located on the
Far Side of the
Moon , beyond the northeastern limb. It lies to the southwest of the larger
Szilard Crater , and southeast of the huge
Fabry -
Harkhebi double walled-plain.
This crater formation has been heavily damaged by a history of impacts, leaving an irregular, battered outer rim. A smaller impact crater has merged into the southern rim and the northern rim is little more than an irregular, arcing range of ridges. The interior is nearly as irregular, and the entire formation is little more than a rugged depression in the surface.
Starting about 30
Kilometer s to the north of Sumner crater and progressing to the east-southeast is a long, linear chain of craters that forms an irregular cleft in the surface. This formation is named ''Catena Sumner'' after the nearby crater. It progresses to the northeast rim of 'Harriot A', a satellite crater of
Harriot .
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 Sumner crater.
