The rim and inner wall of Numerov has undergone considerable erosion, and much of the eastern side is pock-marked by small craterlets. There is a small, very eroded crater attached to the exterior to the southeast, and 'Numerov Z' is nearly connected to the northern rim. The interior floor of Numerov is relatively level, but with a central peak formation at the mid-point and some low ridges just to the south. There are a few gouge-like grooves in the surface in the northeastern floor. The western half of the floor and inner walls have been partly overlaid by ejecta from Antoniadi.
