Denebola star facts

Denebola , also designated Beta Leonis ( β Leonis , abbreviated Beta Leo , β Leo ) is the second-brightest star in the zodiac constellation of Leo , although the two components of the γ Leonis double star are unresolved to the naked eye and have a combined magnitude brighter than β. 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 ly from the Sun. Its apparent visual magnitude is , 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.

The proper motion Wolf 359 against the background is   arcseconds per year, and it is moving away from the Sun at a velocity of 19 km/s. [4] [7] When translated into the galactic coordinate system , this motion corresponds to a space velocity of (U, V, W) = (−26, −44, −18) km/s . [44] The space velocity of Wolf 359 implies that it belongs to the population of old-disk stars . It follows an orbit through the Milky Way that will bring it as close as  kly ( kpc) and as distant as 28 kly ( kpc) from the Galactic Center . The galactic orbit has an eccentricity of , and the star can travel as far as 444 light-years (136 pc) away from the galactic plane . [45] The closest stellar neighbor to Wolf 359 is the red dwarf Ross 128 at   ly (  pc ) away. [46] Approximately 13,850 years ago, Wolf 359 was at its minimal distance of about  ly ( pc) from the Sun. [47]
