Poczobutt is a large lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb in an area occasionally brought into sight due to libration effects.
The crater Zsigmondy overlies the northeastern rim, and Omar Khayyam is located in the western part of Poczobutt's interior.
The outer rim now forms an irregular ring of peaks, broken in several locations by small craters.
Likewise much of the interior floor is irregular due to overlying impacts or their ejecta.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Poczobutt.
