Geological Chronicle
Schomberger is an impact crater in the southern limb region of the Moon, situated southwest of Boguslawsky and southeast of Simpelius. Formed during the Imbrian period, the formation spans a diameter of 85.8 kilometers and retains relatively crisp morphological features that have resisted heavy degradation from minor impacts.
The crater perimeter is roughly circular with a sharp rim. Its complex inner wall displays slumping, terraces, and numerous ridges, descending to an interior floor that is largely level with a rougher western section. At the center of the floor sits a central peak complex composed of multiple distinct ridges.
The crater is accompanied by several satellite formations, including the relatively young, rayed crater Schomberger A bordering its southern rim and the degraded Schomberger C near its western rim. The feature is named for Austrian astronomer and mathematician Georg Schomberger.
