Colongitude	44° at sunrise
Eponym	Rudolf J. E. Clausius

Clausius is a lunar crater that is located in the southwest part of the Moon, in the small lunar mare designated Lacus Excellentiae. It is completely enclosed by the mare material, although the tiny satellite crater 'Clausius A' lies just to the north. The rim of Clausius is low and sharp, with a slightly oval shape that is longer in the north-south direction. The interior floor has been flooded by basaltic lava, and appears level and featureless with a darker surface that matches the mare surface that surrounds the crater exterior.

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 Clausius crater.
