Krusenstern (crater)
Encyclopedia
Krusenstern is a lunar
crater
that lies amidst the battered terrain
in the southern part of the Moon
'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.
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
period, 4.55 to 3.92 billion years ago.
It is named after Adam Johann Krusenstern, an early 19th-century Baltic German
explorer in Russia

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

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...
