Chernyshev is a
lunar impact crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal c ...

The rim of this crater has been worn by impacts, and multiple tiny craters lie along the rim. The southern part of the rim in particular has been more heavily eroded and modified by impacts compared to the northern part of the perimeter. The interior floor is more heavily impacted in the eastern half when compared to the west, although even the later region is not free of small impacts. The floor is otherwise relatively level and lacks a central peak or significant ridges.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Chernyshev.
