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. 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
, being named after this crater.
The rim of Delisle crater 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.
This formation has also been designated "De l'Isle" in some sources.
This is a sinuous rille centered on selenographic coordinates 31.0° N, 32.0° W. It occupies a maximum diameter of 60 km. Three tiny craters in the vicinity of this feature have been assigned names by the IAU
. These are listed in the table below.
||Russian masculine name |
||French masculine name |
||Spanish feminine name |
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.
