Seares (crater)
Encyclopedia
Seares is a lunar
impact crater
located in the northern part of the Moon
's far side. It lies to the east-northeast of the walled plain Schwarzschild
, and to the west of the prominent crater Karpinskiy
.
The rim of this old crater is worn and battered by impacts, and now forms an irregular ring of peaks, valleys and ridges about the interior floor. The satellite crater Seares B lies across the northeastern rim. There are small craters across several other parts of the rim. The northwestern rim and outer rampart of Seares overlies half of an old crater that is nearly as large in radius.
The interior floor is nearly level in places, but is marked by a multitude of tiny craterlets of various dimensions. A series of ridges, grooves, and small craters forms a band across the central part of the floor from west to east.
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...

Karpinskiy (crater)
Karpinskiy is a lunar impact crater that lies in the northern part of the Moon on the far side from the Earth. This crater is concentric with a larger and older formation lying along the southern rim. This combined rim gives Karpinskiy a larger and wider interior wall along its south face...
