Kamerlingh Onnes is a lunar impact crater on the far side of the Moon. It lies less than a crater diameter to the north-northwest of the crater Kolhörster. North of Kamerlingh Onnes lies Shternberg and to the northwest is Weyl. This is a worn and eroded crater formation that is slightly elongated along the east–west direction, giving it a somewhat oval shape. A number of small craters lie along the rim, particularly along the northern side. The interior floor is marked only by a few small craterlets, and some ray material from the crater Ohm to the northeast. References Impact craters on the Moon
