Geological Chronicle
Schuster is an eroded impact crater on the lunar far side, spanning a rim diameter of 100.08 kilometers along the eastern rim of the much larger walled plain Mendeleev. The western half of the rim is its most intact section, where it overlaps Mendeleev. A tight cluster of small craterlets marks the northern inner wall and floor where the crater rim joins the rim of Mendeleev, while the satellite craters Schuster N and Schuster R overlie the southwestern rim edge.
At the midpoint of the crater interior stands a central peak. The peak bears the infrared spectrum of pure crystalline plagioclase, while the eastern half of the floor is pockmarked by small and tiny craterlets.
Prior to naming in 1970 by the International Astronomical Union, the crater was known as Crater 218. The feature is named for Sir Arthur Schuster, a British mathematician and physicist.
