Eponym

This is a heavily worn and eroded crater with a rounded outer rim that is incised and damaged by multiple smaller craters. Little of the original rim still remains besides a rounded and irregular ridge in the surface. The interior floor is also marked by a number of small craters, the most notable being a crater near the south-southeastern inner wall.

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 Roberts.
