Barkla (crater)
Encyclopedia
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. Southwest of Barkla is the crater Lamé
.
The rim of Barkla is very nearly circular, although it is slightly elongated to the northeast and southwest. The wall shows little appearance of erosion from subsequent impacts, and is not overlain by any craterlets of note. At the mid-point of the floor is a central peak, which joins a low ridge running to the south and northeast.

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...

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...

Kapteyn (crater)
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....

Lamé (crater)
Lamé is a lunar impact crater located astride the northeast rim of the crater Langrenus, to the east of Mare Fecunditatis. The eastern crater rim appears overlaid by a series of overlapping craters that form an intermittent chain flowing nearly a hundred kilometers to the south...
