Anaximander (crater)
Encyclopedia
Anaximander is a lunar
crater
that is located near the northwest limb of the Moon
. It is joined at the northern rim by the crater Carpenter
, a younger and better-defined formation. To the southeast is the much larger J. Herschel
, a formation of the variety known as a walled plain.
The outer wall of Anaximander is heavily worn and eroded, with multiple notches and breaks. There is no central peak, but the floor contains several small craterlets and a multitude of tiny pits from minor impacts. This crater has merged with the larger Anaximander D to the south, and there is a wide break in their common rims where they have joined. To the northwest a low rise in the surface is all that separated Anaximander from the much larger satellite crater Anaximander B.
The crater is named for the 6th century BCE Greek philosopher and astronomer Anaximander

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...

Carpenter (crater)
Carpenter is a lunar impact crater in the northern part of the Moon, relatively close to the limb. At this position the crater is foreshortened and appears oval in shape. It is, however, very nearly circular in outline. The outer rampart to the south is adjoined to the old crater Anaximander, and...

J. Herschel (crater)
J. Herschel is large lunar crater of the variety termed a walled plain. It is located in the northern part of the Moon's surface, and so appears foreshortened when viewed from the Earth. The southeastern rim of J. Herschel forms part of the edge of the Mare Frigoris lunar mare. To the northwest is...
