Denebola 五帝座一

Denebola (β Leo, β Leonis, Beta Leonis) is the third brightest star in the zodiac constellation of Leo. It is an A-type main sequence star with 75% more mass than the Sun and fifteen times the Sun's luminosity. Based on parallax measurements from the Hipparcos astrometry satellite, the star is at a distance of about 36 light-years (11 parsecs) from Earth. Its apparent visual magnitude is 2.14, making it readily visible to the naked eye. Denebola is a suspected Delta Scuti type variable star, meaning its luminosity varies very slightly over a period of a few hours.
