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. This crater is a proposed site of Lunar Crater Radio Telescope along with Daedalus crater.[1]
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Saha.
