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 Hausen crater to the east-northeast and the even larger Zeeman crater 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.
The interior of the Doerfel crater is also marked by several tiny craterlets in the otherwise relatively flat surface. There is a very slight central rise near the mid-point.
[edit] Satellite craters
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 Doerfel crater.
