Delisle is a small lunar impact crater in the western part of the Mare Imbrium. It was named after French astronomer Joseph-Nicolas Delisle.[1] It lies to the north of the crater Diophantus, and just to the northwest of the ridge designated Mons Delisle. Between Delisle and Diophantus is a sinuous rille named Rima Diophantus, with a diameter of 150 km. To the northeast is another rille designated Rima Delisle, named after this crater.
The rim of Delisle is somewhat polygonal in form and it has a low central rise on the floor. There is some slight slumping along the inner wall, but overall the rim is still relatively fresh with little appearance of significant wear. The outer rim is surrounded by a small rampart of hummocky terrain.
Delisle is a crater of Eratosthenian age.[2]
This formation has also been designated "De l'Isle" in some sources.
