Celsius is a small lunar impact crater that is located in the rugged terrain in the southern hemisphere on the Moon's near side. It lies less than one crater diameter to the south-southwest of the crater Zagut, and due north of Büsching. Separated by a valley to the east-southeast is the larger Rabbi Levi crater.
This is a heavily worn crater with a southwest rim that has been damaged by multiple small crater impacts. There is a valley-like gap in the northern rim that joins Celsius with Celsius A. The interior floor of Celsius is almost featureless, except for a small craterlet in the northern half.
This crater is named after Swedish astronomer, physicist and mathematician Anders Celsius. His name was introduced into lunar nomenclature by German astronomer and geophysicist J. F. Julius Schmidt in 1878. Its designation was officially adopted by the International Astronomical Union in 1935.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Celsius.
