Artem'ev (crater)
Artem'ev is a lunar crater that is located on the far side of the Moon. The rim of this crater has been modified by subsequent impacts in the vicinity, with an inward bulge along the southwest edge and a worn impact lying across the north rim. The satellite crater Artem'ev G is partly overlain by...

This is a heavily worn crater formation with an outer rim that has been rendered into an uneven, somewhat circular range due to impact erosion. There is a significant outward bulge along the rim edge to the south-southwest. A smaller crater lies across the rim to the west-northwest. The interior floor has low ridges and uneven areas most likely as the result of large deposits of ejecta. There is a cluster of small craters near the mid-point of the interior, and the worn remains of a pair of older impacts in the north and west.
