Gruemberger D (Moon)

Satellite Feature of Gruemberger

Named after Christoph Gruemberger - Austrian astronomer (1561-1636).

Gruemberger is an old impact crater in the southern part. When viewed from the Earth this crater appears oval in shape due to foreshortening, but it is actually circular. The crater lies about 25 kilometers to the north-northwest of the larger and more prominent crater Moretus. The smaller crater Cysatus intrudes into the eastern rim. (wikipedia entry)
