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 a crater diameter due east of the similar-dimensioned Wyld crater, and to the north-northwest of the large Pasteur walled-plain.
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.

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 Saha crater.
