Star Regulushamal Info

Star Regulushamal, also known as Alpha Leonis, is the brightest star in the constellation of Leo and the 60th brightest star in the night sky. It is a main sequence star located approximately 79 light years away from Earth.

The name Regulushamal is a combination of two Arabic words, "Regulus" meaning "little king" and "hamal" meaning "head of the ram". This name was given by ancient Arabic astronomers who saw the star as the "heart of the lion" in the constellation of Leo.

The star was first discovered by the famous Greek astronomer Ptolemy in the 2nd century AD. He catalogued it as one of the four "Royal Stars" along with Aldebaran, Antares, and Fomalhaut.

In 1782, British astronomer William Herschel observed Regulushamal and discovered that it was actually a binary star system, with a faint companion star orbiting around it. The two stars are separated by a distance of about 177 astronomical units (AU), with one orbit taking approximately 600 years to complete.

Regulushamal is classified as a spectral type B7V star, meaning it is a blue-white main sequence star. It has a mass of about 3.5 times that of the Sun and a surface temperature of around 12,000 Kelvin. It is also six times larger and 288 times more luminous than the Sun.

In ancient astrology, Regulushamal was believed to bring success, honor, and wealth to those born under its influence. Today, it continues to captivate astronomers and stargazers alike with its beauty and prominence in the night sky.
