Regulus (α Leo / α Leonis / Alpha Leonis) is the brightest star in the Constellation Leo and One Of The Brightest Stars in the nighttime sky.

Regulus is approximately 77.5 Light Year s from Earth ’s Solar System . Its name is Latin for “prince” or “little king.” It is also known as Qalb Al Asad, from Arabic '''قلب الأسد''' ''qalb {Link without Title} al-´asad'', meaning “the heart of the lion.” This phrase is sometimes approximated as '''Kabelaced''', or translated into Latin as '''Cor Leonis'''.
In Hindu Astronomy , Regulus corresponds to the Nakshatra Magha . Regulus is considered the last first magnitude star in the sky because the next brightest star, Adhara , has a magnitude of 1.50, officially making it a second magnitude star. Of the brightest stars in the sky, Regulus is closest to the ecliptic, and the sun makes its closest approach around August 23 of each year. This fact also means that Regulus is regularly Occulted by the Moon. It’s known as 轩辕十四 (the Fourteenth Star of Xuanyuan) in Chinese. Xuanyuan is the name of Yellow Emperor .
