ray system A ray system comprises radial streaks of fine '' ejecta'' thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter ...

. This ejecta forms a nearly continuous blanket out to at least one crater diameter before forming extended rays and a multitude of wispy markings across the surface. The ray system continues for several hundred kilometers, including extending across a substantial portion of the Korolev basin. Due to these prominent rays, Crookes is mapped as part of the Copernican System. As would be expected for a relatively young crater, Crookes has a sharp-edged rim that has not been significantly eroded. The inner walls are relatively wide, and have slumped inward along the edges. 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.
