Plaskett is a prominent lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies only a few hundred kilometers north of the lunar south pole, and the sunlight it receives is at a low angle. The large Rozhdestvenskiy walled-plain is attached to the southwest rim of Plaskett, between the crater and the pole. To the north is the overlapping Milankovic -Ricco crater pair.

The outer rim of Plaskett has a somewhat polygonal shape formed from outward bulges in the perimeter. The inner wall is terraced along the southern edge, while the remainder is rougher and less finely featured. The interior floor is relatively flat and there is a central peak formed of a double-mount at the mid-point. Satellite crater 'Plaskett U' is attached to the southeast rim.

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 Plaskett crater.
