Kapteyn (crater)
Encyclopedia
Kapetyn is a lunar
impact crater
that is near the eastern limb of the Moon
, to the west of the crater La Pérouse
. West of Kapetyn is the slightly smaller Barkla
, and farther to the west-northwest is the prominent Langrenus
.
This crater is circular in shape, although it appears oval when viewed from the Earth
due to foreshortening. The rim is only slightly worn, with no craters of note along the edge or the inner walls. There is a shelf along the eastern inner wall. At the mid-point of the interior floor is a central peak.
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...

La Pérouse (crater)
La Pérouse is a lunar impact crater that is located near the eastern limb of the Moon. It lies northwest of the larger crater Ansgarius, and to the east of Kapteyn. This crater appears foreshortened due to its location, but the rim is nearly circular when viewed from orbit.The rim of La Pérouse is...

Barkla (crater)
Barkla is a lunar impact crater that lies near the eastern limb of the Moon. It is located to the east of the prominent crater Langrenus, and was formerly designated Langrenus A before being renamed by the IAU. Due east of Barkla is Kapteyn, a formation only slightly larger with a similar size...

Langrenus (crater)
Langrenus is a prominent impact crater located near the eastern lunar limb. The feature is circular in shape, but appears oblong due to foreshortening. It lies on the eastern shore of the Mare Fecunditatis...
