Description
A relatively fresh Copernicus-like crater at high latitude on the farside. It has typical wall terraces and central peaks. The texture on the relatively smooth floor suggests that it has not been infilled by downslope movement of wall materials; possibly it is impact melt. The odd line of 10 or so evenly spaced bumps on the NW edge of the floor is real, for it also appears on the recent SMART-1 image. The bumps line up with a possible lineation just outside the crater wall that roughly points back toward Ricco but I don't know what formed the bumps. - tychocrater Sep 1, 2007

Nomenclature
John Stanley Plaskett (November 17, 1865 – October 17, 1941) was a Canadian astronomer. His formal astronomical career did not start until 1903, when he was appointed to the staff at Dominion Observatory in Ottawa. His achievements are all the more remarkable for this very late start. He measured radial velocities and studied spectroscopic binaries.
