    Based on parallax measurements from the Hipparcos astrometry satellite, the star is at a distance of about 36 light-years 11 parsecs from the Sun. Its apparent visual magnitude is 2. Denebola is a suspected Delta Scuti type variable star , meaning its luminosity varies very slightly over a period of a few hours. It also bears the Flamsteed designation of 94 Leonis assigned on the basis of increasing right ascension rather than luminosity and additional designations followed as the star was recorded in subsequent star catalogues.

    In the Alphonsine Tables it was recorded as Denebalezeth. Proctor 's star chart of the Northern Hemisphere it was designated Deneb Aleet. Denebola, along with Spica and Arcturus , is part of the Spring Triangle asterism, and by extension, also of the Great Diamond together with the star Cor Caroli.

    However, the high rate of rotation results in an oblate shape with an equatorial bulge. Denebola shows a strong infrared excess , which most likely means there is a circumstellar debris disk of cool dust in orbit around it. Kinematic studies have shown that Denebola is part of a stellar association dubbed the IC supercluster.

    All the stars of this group share a roughly common motion through space, although they are not gravitationally bound. This suggests that they were born in the same location, and perhaps initially formed an open cluster.

    In total more than sixty probable members of the group have been identified. In astrology , Denebola was believed to portend misfortune and disgrace. From Wikipedia, the free encyclopedia.
