Chi Leonis

Chi Leonis, Latinized from χ Leonis, is a double star in the constellation Leo. It is visible to the naked eye with an apparent visual magnitude of 4.63. The distance to this star, as determined using parallax measurements, is around 95 light years. It has an annual proper motion of 346 mas. This is most likely a binary star system. The primary component has a stellar classification of F2III-IVv, which at first would classify it as a F-type star between the giant and subgiant evolutionary stages, but evolutionary models suggest the star is instead in the main sequence. It has an estimated 162% of the Sun's mass and nearly twice the Sun's radius. The companion is a magnitude 11.0 star at an angular separation of 4.1″ along a position angle of 264°, as of 1990.
