Saha is alunar impact crater on theMoon'sfar side, behind the eastern limb as seen from theEarth. It lies less than one crater diameter due east of the similar-sizedWyld, and to the north-northwest of the large walled plainPasteur.

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 someterrace-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 ofLunar Crater Radio Telescope along withDaedalus crater.^[1]

Satellite craters

[edit]

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.
