Crookes is a lunar impact crater that lies on the Moon's far side as seen from the Earth.

The rim of this crater has a relatively high albedo compared to most such formations on the Moon, and it lies at the center of a ray system.

The ray system continues for several hundred kilometers, including extending across a substantial portion of the Korolev basin.

Offset slightly to the east of the midpoint of the crater is a small central peak on the interior floor.

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