Eponym Samuel A. Saunder

Saunder is a lunar crater located in the central highland region of the Moon, to the east-northeast of the walled plain Hipparchus, named after Samuel Arthur Saunder. The outer wall is irregular and broken in several locations, forming the overall shape of a pentagon. The interior of Saunder has been flooded with lava, forming a level surface just below the rim. The floor lacks a central peak, but there are low rises in the southeast quadrant and a tiny craterlet towards the north rim.

One other crater, smaller is about 35 km nearly to the northwest and is Pickering, also around 55 km north-northeast is the larger Lade and about 120 km southeast is Lindsay.

Its diameter is 45 km long and is 1,300 meters deep, also, the area is around 1,200 km².

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Saunder. Saunder A is located far east close to Theon Senior Crater, Saunder B is east-northeast next to the main crater, Saunder C is to the northeast, Saunder C is to the east-north east and Saunder T is to the east.
