Numerov (crater)
Encyclopedia
Numerov is a lunar
impact crater
that is located on the Moon
's far side, deep in the southern hemisphere
. It is attached to the larger and younger crater Antoniadi
to the west, and the outer rampart of Antoniadi overlies the inner wall and part of the western interior floor of Numerov. To the east-southeast is the larger walled plain Zeeman
, and to the east-northeast is the old crater Crommelin
.
The rim and inner wall of Numerov has undergone considerable erosion, and much of the eastern side is pock-marked by small craterlets. There is a small, very eroded crater attached to the exterior to the southeast, and Numerov Z is nearly connected to the northern rim. The interior floor of Numerov is relatively level, but with a central peak formation at the mid-point and some low ridges just to the south. There are a few gouge-like grooves in the surface in the northeastern floor. The western half of the floor and inner walls have been partly overlain by ejecta from Antoniadi.
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...

Sphere
A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point...

Antoniadi (lunar crater)
Antoniadi is a large lunar impact crater that lies on the southern hemisphere on the far side of the Moon. The crater intrudes into the southeastern rim of the crater Minnaert, a slightly smaller formation that is significantly more eroded. Attached to the eastern rim of Antoniadi is Numerov,...

Zeeman (crater)
Zeeman is a lunar impact crater located on the far side of the Moon near its south pole. It is not directly visible from the Earth. To the northwest of Zeeman lies the crater Numerov. Southeast of the rim is the crater Ashbrook....

Crommelin (lunar crater)
Crommelin is an ancient lunar crater that is located in the vicinity of the south pole of the Moon, on the far side. It lies to the north of the large crater Zeeman, and to the east-northeast of Numerov....
