Denebola

Star type
g A3 V

Distance from Earth
g 36.2 ly

Star Service No.
g NA

Age
g Less than 400 million years

Diameter/Mass/Temp (xSol)
g 173% (high rate of rotation of this star results in an oblate shape with an equatorial bulge); 175%; 8500 K

Picture of star
g NA

Star system features
g Part of a stellar association dubbed the IC 2391 supercluster. All the stars of this group share a roughly common motion through space, although they are not gravitationally bound. This implies that they were born in the same location, and perhaps initially formed an open cluster. Other stars in this association include Alpha Pictoris, Beta Canis Minoris and the open cluster IC 2391.

Known planets
g Shows a strong infrared excess, which means there must be a debris disk of cool dust in orbit around it

Habitable zone
g Much too young to support an an Earth-like planet
