Eponym	John D. Cockcroft

Cockcroft is a lunar crater that is situated on the far side of the Moon from the Earth, so that it has only be observed and photographed from orbit. It lies to the northeast of the larger crater Fitzgerald, and southeast of Evershed.

The rim of this crater is worn and eroded from subsequent impacts. The satellite crater Cockroft N is intruding into the south-southwestern rim. There are small craters along the rim to the southeast, east, and north-northwest, and a small crater lies along the eastern inner wall. The interior floor is uneven in places, particularly in the southern half, and contains multiple small and tiny craterlets.

Satellite craters

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 Cockcroft.
