Comstock is a lunar impact crater that is located on the far side of the Moon.

It lies to the northeast of the walled plain Fersman, and north of the crater Weyl.

One of these lies attached to the inner side of the rim and inner wall, extending part way across the floor.

The interior floor is marked by several tiny craterlets, and traces of ray material from the crater Ohm to the east-southeast.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Comstock.
