Paneth is a lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb.
The rim of Paneth is worn, but only moderately; the edge remains well-defined and marked only by small craters along the northwest and southeast.
Only a narrow strip of terrain separates Paneth from Smoluchowski, and this ground is marked by an elongated crater and a short rille.
The interior floor has a central peak formation near the midpoint and a pair of small craters along the eastern rim.
By convention, these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Paneth.
