Delisle (crater) - Definition and Overview

Delisle is a small lunar crater in the western part of the Mare Imbrium. It lies to the north of the Diophantus crater, and just to the northwest of the ridge designated Mons Delisle. The crater rim is somewhat polygonal in form and it has a low central rise on the floor.

In the proximity of this crater are a pair of rilles. To the northeast is the Rima Delisle, a sinuous rille with a length of about 50 kilometers. To the south between Deslisle and Diophantus craters is the sinuous rille designated Rima Diophantus, a feature with a length of about 140 kilometers.

This formation has also been designated "De l'Isle" in some sources.

Satellite craters

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 Delisle crater.
