Tags: Crater.
Saunder is a lunar crater located in the central highland region of the Moon to the east-northeast of the walled plain Hipparchus. 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.
