Carpenter (crater)
Encyclopedia
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 the satellite formation Anaximander B lies along the western rim. To the northeast is Anaximenes
.
In geological terms Carpenter is a somewhat young lunar crater, with features that have not been significantly eroded by subsequent impacts. Certainly it is much younger than the surrounding crater formations. The inner wall displays an appearance of slumping, particularly along the eastern face, and there is some development of terraces. The outer rim is unmarked by craterlets of note, but there is a small crater along the south-southeastern inner wall.
The interior floor within the sloping inner walls is generally level, but irregular with many small bumps and hills. Near the mid-point is an unusual double central peak formation, with a smaller peak offset to the west and a larger ridge offset to the east. The latter ridge runs southward to the edge of the inner wall.
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...

Anaximander (crater)
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...

Anaximenes (crater)
Anaximenes is a low-rimmed lunar crater that is located near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon....
