Notes
Regulus is the brightest object in the constellation Leo and one of the brightest stars in the night sky. It has the Bayer designation designated α Leonis. The spectroscopic binary Regulus A consists of a blue-white main-sequence star and its companion, a pre-white dwarf. Regulus BC, also known as HD 87884, is separated from Regulus A by 176″ and is itself a close pair.Regulus is a multiple star system consisting of at least four stars and a substellar object. Regulus A is the dominant star, with a binary companion 177" distant that is thought to be physically related. Regulus D is a 12th magnitude companion at 212",[34] but is an unrelated background object.[35]
