This crater is a circular formation with a low rim and a relatively featureless inner wall and interior floor. There are some tiny craterlets around the rim, including one across the northwest wall and another on the inner wall to the south. The interior has no significant features, with only a tiny craterlet to mark the surface.
Rost lies east of the Schiller-Zucchius Basin, and the outer rim of the basin lies between Rost and Rost A.
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 Rost.
