What is "anuchin"

Anuchin is a lunar impact crater that lies on the southern hemisphere on the far side of the Moon. It is located to the south of the larger crater Lamb, and to the north-northwest of Kugler.

The rim of Anuchin remains relatively sharply defined, although it has been subject to wear due to subsequent impacts. The satellite crater Anuchin L lies astride the southern rim, but the otherwise the outer wall is not significantly incised. The interior floor is nearly featureless, with no central peak at the midpoint and only a few tiny craterlets. But it does not possess the darker hue of a crater interior that has been resurfaced by lava flows.
