EponymMax Planck

Planck is a large lunar impact crater, approximately 319 kilometers in diameter, that is located in the southern hemisphere of the Moon, on the far side as seen from the Earth.[1] It lies to the west of the walled plain Poincaré, another enormous formation only slightly larger than Planck. Lying across the southeast rim of Planck is the crater Prandtl, to the northeast is Hildegard, and to the west is Fechner. Planck is located within the South Pole–Aitken basin.[2]
