Michelson is a crater on the far side of the Moon. It lies along the northeastern outer rim of the huge walled plain Hertzsprung, and to the southwest of the crater Kolhörster. This is a heavily eroded crater formation with multiple impacts along the rim edge and within the interior. The rim is roughly circular, but has been rendered relatively uneven due to these smaller craters. There are small craters across the interior floor, including impacts along the north, west and southeastern edges.
