The name 'Regulus' comes from Latin and means 'prince' or 'young king'. In Arabic it was known as 'Qalb Al Asad' قلب الأسد, which means 'the heart of the lion'. In China it was known as 轩辕 十四, the Fourteenth Star of Xuanyuan, the Yellow Emperor. In Babylon it was known as 'Sharru', which means 'the king'. In Persia it was known as 'Miyan', which means 'the center' and also as 'Venant', one of the four real stars of the Persian monarchy.
It is part of the group of Behenian stars, a selection of fifteen stars in the medieval astrology of Europe and the Arab world.
Regulus is a blue-white subgigant star of spectral type B8 IV, with a surface temperature of 12460 K. It has a rotation speed of 347 km/s. Its speed of rotation is extremely fast (15.9 hours), due to which has a very ovaloide and a photosphere much more warm and luminous in the poles. It is very close to the limit, if its rotation speed was a 15% faster, the gravity of the star would not be sufficient to contain its material.
It is a multiple system, consisting of 3 components: the main white-blue star, a white dwarf that orbits it, and at 5000 AU another couple, formed by an orange and a red dwarf, separated each other by approximately 100 UA.
Photometric observations were carried out in the years 2005, 2008, 2009 and 2014.
In July of 1959, coinciding with the Walt Disney movie "Sleeping Beauty" (1959), Venus occulted Regulus.
