Donner S (Moon)

Satellite Feature of Donner

Named after Anders Severin Donner - Finnish astronomer (1854-1938).

Donner is a lunar crater on the far side. It is located just to the northeast of the Mare Australe, behind the southeastern limb. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen. This crater has a moderately eroded outer rim, and several small and tiny craterlets lie along the edge. (wikipedia entry)
