Saha (crater)
Encyclopedia
Saha is a lunar
impact crater
on the Moon
's far side, behind the eastern limb as seen from the Earth
. It lies less than one crater diameter due east of the similar-sized Wyld
, and to the north-northwest of the large walled plain Pasteur
.
This crater has been worn and damaged by subsequent impacts, including the satellite crater Saha W which lies across the northwest rim and inner wall. The inner sides still display some terrace-like shelf structures, but these have become worn and have lost definition. There is a small, bowl-shaped crater Saha M in the southwestern part of the interior floor. To the north of this feature is an arcing ridge feature. The floor is otherwise pitted by various tiny craterlets.
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...

Wyld (crater)
Wyld is a lunar impact crater that is located on the Moon's far side, beyond the eastern limb. It lies in that portion of the lunar surface that is sometimes brought into view of the Earth under conditions of favorable libration and illumination, but even then the crater is seen from the edge and...

Pasteur (lunar crater)
Pasteur is a large lunar crater belonging to the category termed a walled plain. It lies on the far side of the Moon as seen from the Earth, just beyond the eastern limb. The vicinity of this crater is occasionally brought into view from Earth due to librations, although not much detail can be...
