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." It is also known as Al Kalb Al Asad, from Arabic '''القلب الأسد''' ''al-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'''.

This fact also means that Regulus is regularly Occulted by the Moon.

This pair is separated from the much larger Regulus A by about 4,200 AU and the orbit the main star with a period of over 130,000 years.
