Argelander (crater)
Encyclopedia
Argelander is a lunar
impact crater
that is located in the south-central highlands of the Moon
. It lies in the midpoint between the smaller crater Vogel
in the north and the larger Airy
to the south. To the northwest is the worn remnant of Parrot
. Just to the west is a shallow cleft in the surface that follows a course to the north-northwest, intersecting the southeast rim of Parrot.
The rim of Argelander is somewhat worn and indented, although less distorted than Airy to the south. The bottom is relatively flat and there is a small central rise. There is a curved depression in the surface following the western rim, giving the wall a rampart on that side.
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...

Vogel (lunar crater)
Vogel is a small lunar impact crater located to the southeast of Albategnius. It is the smallest member of a trio of craters that increase in size from north to south, consisting of Vogel, Argelander and Airy. To the west is the remnant of the crater Parrot....

Airy (lunar crater)
Airy is a lunar impact crater located in the southern highlands. It is named in honour of British astronomer George Biddell Airy. It forms the southern-most member of a chain of craters consisting of Vogel, Argelander, and Airy. A little further to the south lies Donati. Airy has a worn, and...

Parrot (crater)
Parrot is the remains of a lunar crater that has been almost completely worn away. It is attached to the southern rim of the crater Albategnius, and is located among the rugged highlands among the south-central part of the visible Moon...

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 Argelander.| Argelander | Latitude | Longitude | Diameter |
