描述
English: en:Mare Humorum is a small circular mare on the lunar nearside.

It is about 275 miles across. The mountains surrounding Mare Humorum mark the edge of an old impact basin. This basin has been flooded and filled by mare lavas. These lavas also extend past the basin rim in several places. In the upper right are several such flows which extend northwest into southern Oceanus Procellarum.

The rather large crater to the north of the mare is Gassendi. The crater on the southeastern rim of the basin is Doppelmayer. The light grey feature that protrudes into the

mare from the southeast is Promontorium Kelvin.
