gulus: The Heart of the Lion" Regulus is the star at the heart of the Leo constellation and is one of the brightest stars in the night sky. It is a blue-white main sequence star, situated approximately 79 light-years away from Earth. Its name means "Little King" or "Prince" in Latin. Regulus is a fascinating star known for its fast rotation, which causes it to spin at a rate of 90 kilometers per second at its equator, making it one of the fastest rotating stars known to man. This rapid rotation means that Regulus is slightly flattened at the poles, similar to how the Earth is flattened at its poles. Regulus is a binary star, meaning it has a companion star orbiting around it. The two stars are extremely close, with the smaller star orbiting the larger one every 40 days. This companion star was discovered in 2006, and its presence was unexpected, as it was difficult to detect due to the brightness of Regulus. In ancient times, Regulus was associated with royalty and was regarded as a symbol of power and strength. In astrology, it is associated with the zodiac sign of Leo, and those born under this sign are believed to be confident, ambitious, and charismatic.
