. It is located to the north-northeast of the walled plain
Mach. To the northwest of Joule is the crater
Blazhko.
This is a worn and eroded crater formation. A pair of smaller craters lies along the northeastern rim, and a crater is intruding into the northwest rim. To the south is an outward projection that has the appearance of a crater partly overlain by Joule. The remainder of the rim and inner wall is somewhat irregular. The interior floor is more level than the terrain surrounding the crater, but is marked by some small craterlets. At the midpoint of the interior floor is a central peak.
Joule T is located less than a crater diameter to the west of Joule. A smaller crater named

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Joule.
