Vavilov is a prominent impact crater that is located to the west of the Hertzsprung impact basin. It is located on the far side of the Moon and can not be viewed directly from the Earth. About a crater diameter to the northwest is the smaller Chaucer crater, and further to the southwest is the Sechenov crater.

This is a relatively young impact that still retains the faint remnants of a ray system. Just outside the rim is a shadowed area, with the rays beginning about one-third of a crater diameter distant. The faint rays extend for several crater diameters in all directions.

Vavilov is a well-defined feature that has undergone a minimum of erosion due to subsequent impacts. The outer rim is roughly circular, with a pair of slight outward bulges to the southeast. The inner walls of the rim display several s, particularly to the southeast. The interior floor is roughly level, with a central ridge offset to the west of the mid-point, and some low hills in the southeast.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Vavilov crater.
