Is denebola a white dwarf?
Denebola has the stellar classification A3Va, indicating a hydrogen-fusing dwarf appearing white in colour. The luminosity class “Va” indicates that it is highly luminous for a main sequence star. Its estimated age is between 100 and 380 million years.
Is denebola visible to naked eye?
Based on parallax measurements from the Hipparcos astrometry satellite, the star is at a distance of about 36 light-years from the Sun. Its apparent visual magnitude is 2.14, making it readily visible to the naked eye.

Is denebola a giant star?
Denebola is a main-sequence star of spectral type A3Va, it is a particularly luminous dwarf generating energy through nuclear fusion at its core. It has an apparent magnitude of 2.113 and an absolute magnitude of +1.93. It is also a suspected Delta Scuti variable star.
Is denebola bigger than the sun?
Denebola is a relatively young star with an age estimated at less than 400 million years. Interferometric observations give a radius that is about 173% that of the Sun. It has 75% more mass than the Sun, which results in a much higher overall luminosity and a shorter life span on the main sequence.
How did Leo get its name?
