Definitions for "Boltzmann"
Boltzmann is an old lunar crater that is located along the southern limb of the Moon, in the vicinity of the south pole. At this location the crater is viewed from the side from Earth, and so not much detail can be seen. It is located to the north of the Drygalski walled-plain, and to the east of the Le Gentil crater.
