Heis (crater)

Heis is a small lunar impact crater that is located in the western part of the Mare Imbrium. It was named after German astronomer Eduard Heis.^[1] It is located to the northeast of the crater Delisle, and south of C. Herschel. Due east is the wrinkle ridge Dorsum Heim. Heis is a circular, symmetrical formation with an interior floor that is about half the diameter of the outer rim. The tiny satellite crater Heis A intrudes slightly into the northern rim.
