Werner (crater)
Werner is a prominent lunar impact crater that lies in the rugged south-central highlands of the Moon. It is almost joined with the crater Aliacensis to the southeast, and the pair form a rugged valley in the intervening gap. Due west of Werner is the distorted Regiomontanus, and to the north is...

Krusenstern is 47 kilometers in diameter, and its walls reach a height of 1,600 meters.
Its outer rim has been heavily worn by impact erosion, leaving an irregular ring of rising ridges and an inner wall incised by impacts. A joined pair of craters, including Krusenstern A, lie along the eastern rim. The interior floor of Krusenstern is a nearly featureless plain, marked only by a few tiny craterlets. The crater is from the Pre-Nectarian
