A narrow lunar sea that runs from west to east across the northern polar regions of the Moon, at least on the face visible from Earth. The lunar Alps run along its southern edge, separating it from the Mare Imbrium beyond, though a long narrow cleft, the Vallis Alpes, runs through the mountains between the two seas. The most prominent crater in the Sea of Cold, and indeed the only crater of appreciable size, is the terrace-walled Aristoteles near the sea's eastern end.
