Delisle is a small lunar crater in the western part of the Mare Imbrium. Selenographic coordinates are used to refer to locations on the surface of Earth 's Moon. Joseph-Nicolas Delisle ( April 4, 1688 Paris - 1768 Paris) was a French Astronomer. In the broadest sense the term impact crater can be applied to any depression natural or manmade resulting from the high velocity impact of a projectile with larger body Mare Imbrium, Latin for "Sea of Showers" or "Sea of Rains" is a vast Lunar mare (mahr'-ay filling a basin on Earth 's Moon It lies to the north of the Diophantus crater, and just to the northwest of the ridge designated Mons Delisle. Diophantus is a lunar Impact crater that lies in the southwest part of the Mare Imbrium. Between Delisle and Diophantus is a sinuous rille named Rima Diophantus, with a diameter of 150 km. Rille (German for 'groove' is typically used to describe any of the long narrow depressions in the lunar surface that resemble channels. 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. In Geometry a polygon (ˈpɒlɨɡɒn ˈpɒliɡɒn is traditionally a plane figure that is bounded by a closed path or circuit 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.
Rima Delisle
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.
| Crater | Longitude | Latitude | Diameter | Name source |
|---|---|---|---|---|
| Boris | 30. 6° N | 33. 5° W | 4 km | Russian masculine name |
| Gaston | 30. Russian ( transliteration:,) is the most geographically widespread language of Eurasia, the most widely spoken of the Slavic languages 9° N | 34. 0° W | 2 km | French masculine name |
| Linda | 30. French ( français,) is a Romance language spoken around the world by 118 million people as a native language and by about 180 to 260 million people 7° N | 33. 4° W | 1 km | Spanish feminine name |
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.
