Doerfel (crater)

Doerfel

Diameter	68 km
Depth	Unknown
Colongitude	111° at sunrise
Eponym	Georg S. Doerfel

Doerfel is a lunar impact crater that is located in the vicinity of the southern pole, just on the far side of the Moon. It lies approximately midway between the large crater Hausen to the east-northeast and the even larger Zeeman to the southwest.

The outer wall of Doerfel retains much of its original form, but it has been rounded and slightly eroded by a history of subsequent bombardment. Many tiny craterlets lie on or near the rim, especially along the westrern edge. There is a slight outward extrusion in the southern rim, and the opposite, northern rim appears somewhat jumbled and eroded.

Doerfel's interior is also marked by several tiny craterlets in the otherwise relatively flat surface. There is a very slight central rise near the midpoint.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Doerfel.
