Neison is a lunar crater that lies to the south of the Meton crater, in the northern part of the Moon. The high latitude of this crater means that the crater appears foreshortened when viewed from the Earth, having an elliptical appearance even though it is nearly circular in shape.
The outer rim of this crater has been heavily worn and eroded by smaller impacts, leaving only a low, uneven ridge surrounding the interior. There are several breaks in this rim, and the inner edge is notched by impacts. The interior has been resurfaced, covering the floor many of these peripheral impacts. The result is a level plain within the shallow rim, with clefts to the southwest, southeast, and east-northeast. Only a few tiny craterlets mark this otherwise featureless floor.

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 Neison crater.
