This article is about the crater on the Moon. See also Nicholson (crater).Nicholson is a lunar impact crater located at the western limb. In this position it is subject to libration which can limit observation. The crater is also viewed at a very oblique angle so it is seen from the side when observed from the Earth. It is an irregular somewhat pear-shaped formation that has an uneven rim due to its location amidst rugged ground.
