It has a white hue and is visible to the naked eye with an apparent visual magnitude of 4.74.[2] The star is located at a distance of is approximately 200\u00a0light years based on parallax,[1] and it is drifting further away with a radial velocity of +3.4\u00a0km\/s.[4]This object is an A-type main-sequence star with a stellar classification of A1\/2V.[3] It has a high rate of spin with a projected rotational velocity of 141[6] to 165\u00a0km\/s, giving it an equatorial bulge that is 4% larger than the polar radius.[11] The star is 482\u00a0million years old with 2.55[6] times the mass of the Sun and around 2.2[7] times the Sun’s radius. It is radiating 41[5] times the luminosity of the Sun from its photosphere at an effective temperature of 9,230\u00a0K.[6] The chemical abundance of the star’s outer atmosphere is similar to that in the Sun.[8]References[edit]^ a b c d e f Van Leeuwen, F.
