Delaunay (crater)
Encyclopedia
Delaunay is a lunar
crater
. The craters La Caille
to the southwest and Faye
to the northeast border on the outer rim of Delaunay. Further to the northwest is the prominent Arzachel
.
This is an irregular crater formation that has an interior ridge running from the northeast side that divides the crater nearly in half, and gives it a heart-shaped appearance. This ridge grows increasingly slender as it approaches the southwest rim, until it terminates at sharp point, giving it the appearance of a curved fang. The outer rim of this crater is equally irregular, and the uneven inner wall varies significantly in width. The southern rim in particular has been heavily damaged by impacts, including La Caille E which intrudes into the interior.
Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Impact crater
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 a larger body...

La Caille (crater)
La Caille is a lunar crater located in the rugged south-central highlands of the Moon. It is located to the northeast of the crater Purbach. Nearly attached to the southeast rim are the remains of Blanchinus, and the two are separated by a rugged stretch of terrain...

Faye (crater)
Faye is a heavily eroded lunar crater in the rugged southern highlands of the Moon. It is attached to the northeastern rim of the crater Delaunay, with Donati located just a few kilometers to the northeast...

Arzachel (crater)
Arzachel is a relatively young lunar impact crater located in the highlands in the south-central part of the visible Moon, close to the zero meridian . It lies to the south of the crater Alphonsus, and together with Ptolemaeus further north the three form a prominent line of craters to the east of...
