Slipher is a lunar impact crater that is located in the northern latitudes on the far side of the Moon. The crater overlies the southwestern outer rim of the much larger walled plain D’Alembert and it occupies a portion of the interior floor of D’Alembert. To the south-southeast is the crater Langevin.Because it overlies D’Alembert Slipher is a younger formation and it has undergone much less erosion. The rim is circular but has a somewhat irregular edge.
