1216 Askania, provisional designation 1932 BL, is a stony main-belt asteroid discovered on January 29, 1932, by Karl Reinmuth at Heidelberg Observatory, Germany.[1] The S-type asteroid is a member of the Flora family, the largest of all known asteroid families.[4]
Light curve observations show a periodicity of 6.536±0.003 hours, during which time the brightness of the body varies by 0.30±0.03 in magnitude.[3]
It was named after "Askania Werke AG", a manufacturer of optical and astronomical instruments in Berlin (also see Cinetheodolite).[1] The company went on to develop the auto pilot of the V-1 bomb in the following years.[5]
