Geiger Crater ( lat. Geiger ) - a large young impact crater in the southern hemisphere of the far side of the moon . The name was given in honor of the German physicist Hans Wilhelm Geiger (1882–1945) and approved by the International Astronomical Union in 1970. The formation of the crater dates back to the late Imperial period [1] .

Crater Description
The nearest neighbors of the crater are the Beyerink crater in the west, the Keeler crater in the northeast, the Heaviside crater in the east-northeast; Zwicky crater in the east, Paracelsus crater in the south-south-east, Cyrano crater in the south, and Arminsky crater in the south-south-west [2] . The selenographic coordinates of the center of the crater are , diameter 36.6 km [3] , depth 2.1 km [4] .
The crater has a polygonal shape, moderately destroyed. The crater rampart is well defined except for the southeastern part where it is flattened. The inner slope of the shaft has the greatest width in the northern part, reaching, together with talus at the foot of a third of the bowl of the crater. The average height of the crater shaft above the surrounding area is 960 m [4] , the volume of the crater is approximately 820 km³ [4] . The bottom of the crater bowl is relatively flat, marked by several small craters.
