Minnaert (crater)
Encyclopedia
Minnaert is a large lunar
crater
that is located on the far side of the Moon
, deep in the southern hemisphere
. It is partly overlain along the southeastern side by the larger and younger crater Antoniadi
. To the west-northwest lies Lyman
.
Nearly half the crater is overlain by the rim, outer rampart, and ejecta from Antoniadi. The remaining rim is worn and eroded, with a number of small craterlets along the edge and inner wall. The western interior floor is relatively level, but is marked by ejecta and secondary cratering from Antoniadi. If the crater ever possessed a central ridge, it may now be buried.
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,...

Lyman (crater)
Lyman is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. It is located to the south of the huge walled plain Poincaré, and to the northeast of Schrödinger, another walled plain...

Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Minnaert.Minnaert | Latitude | Longitude | Diameter |
