Nobile (crater)
Encyclopedia
Nobile is a lunar
crater
that is located near the southern pole
of the Moon
. It lies to the south of the crater Scott
, along the western rim of Amundsen
. Between Nobile and the southern pole
lie the smaller craters Shoemaker
and Faustini
.
This is an eroded crater formation that is almost constantly cloaked in deep shadows. When sunlight does enter the interior of this crater, it does so at a very oblique angle. The crater rim is overlaid by several lesser craters, the most notable being a formation about half the diameter of Nobile along the western rim. There are also small craters along the southwest and northern parts of the rim. The outer rampart of Amundsen overlies the eastern rim and inner wall. The interior floor of this crater is somewhat irregular, and there are a few small craterlets across the surface.
Nobile was previously designated Scott A before being assigned a name by the IAU

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...

Lunar south pole
The lunar south pole is of special interest to scientists because of the postulated occurrence of ice in permanently shadowed areas. Of the lunar poles, the south pole is of greater interest because the area that remains in shadow is much larger than that at the north pole. The lunar south pole...

Scott (crater)
Scott is a lunar impact crater near the south pole of the Moon. Its location close to the lunar limb hinders observation, both from the foreshortening of the crater as seen from Earth and from the limited sunlight that enters the basin. In fact the northern end of this crater is in near perpetual...

Amundsen (crater)
Amundsen is a large lunar impact crater located near the south pole of the Moon, named after the Norwegian explorer Roald Amundsen. It lies along the southern lunar limb, and so is viewed from the side by an observer on the Earth. To the northwest is the crater Scott, a formation of similar...

Shoemaker (lunar crater)
Shoemaker is a lunar crater that is located near the southern pole of the Moon, within half a crater diameter of Shackleton. It lies to the south of the crater Malapert, to the east of Haworth, and just to the west of the similar-sized Faustini. The rim of Shoemaker is circular and worn, with some...

Faustini (crater)
Faustini is a lunar crater that lies near the south pole of the Moon. It is located nearly due south of the much larger crater Amundsen, and is almost attached to Shoemaker to the southwest. About one crater diameter due south is the smaller crater Shackleton at the south pole...
