Etymology: Lat. regule, Fr.
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, which is Latinized to Alpha Leonis, and abbreviated Alpha Leo or α Leo. Regulus appears singular, but is actually a quadruple star system composed of four stars that are organized into two pairs. The spectroscopic binary Regulus A consists of a blue-white main-sequence star and its companion, which has not yet been directly observed, but is probably a white dwarf. The system lies approximately 79 light years from the Sun. HD 87884 is separated from Regulus by 176″ and is itself a close pair. Regulus, along with five slightly dimmer stars (Zeta Leonis, Mu Leonis, Gamma Leonis, Epsilon Leonis, and Eta Leonis) have collectively been called 'the Sickle', which is an asterism that marks the head of Leo.
Regulus can have different meanings depending on the field. However, in general, it refers to: 1. A principle, pattern, or standard by which something is regulated or measured. 2. In astronomy, it is the brightest star in the constellation Leo. 3. In chemistry, it refers to a crude metal or a small but rich portion of a mineral substance primarily used in the earlier ages e.g. "Regulus of Antimony." 4. In history, it was also the title of various Roman and Byzantine officials. 5. Additionally, it's the genus of the Kinglet species of birds. The specific meaning of the term would, therefore, depend on the context in which it is being used.
