Boltzmann (crater)
Encyclopedia
Boltzmann is an old lunar
crater
that is located along the southern limb of the Moon
, in the vicinity of the south pole. At this location the crater is viewed from the side from Earth
, and so not much detail can be seen. It is located to the north of the walled plain Drygalski
, and to the west of the crater Le Gentil
.
This formation has become eroded by many tiny impacts, leaving the features rounded and worn. Little of the original rim still stands above the surrounding terrain, leaving only a depression in the surface. The interior is relatively flat, with a rougher surface in the eastern half. There are several tiny craterlets on the crater interior, including a pair near the southwest inner wall and a small, bowl-shaped crater close to the eastern rim. Offset slightly to the northeast of the mid-point of the floor is a low central peak, now little more than a rounded hill.
To the southeast of the crater rim is an arcing catena formation of tiny craterlets that joins the rim of Boltzmann to the northern rim of Drygalski.
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...

Drygalski (crater)
Drygalski is a large lunar impact crater that lies along the southern limb of the Moon. It partly overlies the crater Ashbrook to the west on the far side of the Moon. Just to the north of Drygalski is the smaller Boltzmann. The location of this crater restricts its observation from the Earth, and...

Le Gentil (crater)
Le Gentil is a lunar crater that is located in the south-southwest part of the Moon, near the limb, and is nearly attached to the southern rim of the huge walled plain Bailly. To the southeast is the large crater Drygalski...
