Regulus (Alpha Leonis) is the brightest star in the constellation Leo and the 21st brightest star in the sky as seen from Earth. Regulus is a bluish-white B star; its Latin name means "the little king" – the reference to a kingly star going back to ancient times. Regulus marks the bottom of the Sickle that outlines the Lion's head, and lies almost exactly on the ecliptic so that it is regularly occulted by the Moon.
