Joule is a lunar impact crater that lies on the far side of the Moon. 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.
