Paneth is a lunar impact crater on the far side , just beyond the northwestern limb. It lies just to the north-northeast of the crater Smoluchowski, and to the east-southeast of Boole on the near side. The rim is worn but not inordinately so; the edge remains well-defined and marked only by small craters along the northwest and southeast. This formation partly overlies a shallower crater Paneth K along the southeast of the rim. (wikipedia entry)
