's near side. Nearly attached to the east-southeast rim is the crater Apianus. Less than one crater diameter to the southwest is the prominent Werner. Krusenstern is intruding into a large circular plain to the north designated Playfair G. Playfair itself lies to the northeast. Krusenstern is 47 kilometers in diameter, and its walls reach a height of 1,600 meters.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. 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
