Plana is a lunar crater that lies on the boundary between two small lunar mare areas with Lacus Mortis to the north and the larger Lacus Somniorum on the southern side. It is joined to the crater Mason to the east by a short stretch of rugged ground. Due north of Plana in the midst of the Lacus Mortis is the prominent crater Bürg.This is a crater with a slender outer rim that has been worn and eroded by impacts.
