Brunner (crater)
Encyclopedia
Brunner is a lunar
impact crater
that is located along the eastern limb of the Moon
, to the southeast of the Mare Smythii
. At this location the crater is viewed from the edge, and so it is not possible to see much detail from the Earth
. The visibility of this formation is also affected by libration
. The crater lies to the southwest of the walled plain Hirayama
, and to the east of the elongated crater Houtermans
.
The rim of Brunner is well-defined and nearly circular, although there is a slight outward bulge and a depressed wall along the north. The interior of the crater is rugged and irregular, with a central ridge formation at the mid-point. There is also a ring-like formation on the floor that is concentric with 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...

Mare Smythii
Mare Smythii is a lunar mare located along the equator on the easternmost edge of the lunar near side. The Smythii basin where the mare is located is of the Pre-Nectarian epoch, while the surrounding features are of the Nectarian system...

Libration
In astronomy, libration is an oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth, or of Trojan asteroids relative to planets.-Lunar libration:...

Hirayama (crater)
Hirayama is a large lunar crater that is located on the far side of the Moon, just beyond the eastern limb. This region of the surface is sometimes brought into view from Earth during periods of favourable libration. However it is best viewed from orbit. This crater is located along the...

Houtermans (crater)
Houtermans is a lunar crater that is located beside the eastern limb of the Moon, in the region of the surface where visibility is affected by libration. It lies to the east of the crater Kreiken, and south of the crater pairing of Helmert and Kao....
