It is visible to the naked eye with an apparent visual magnitude of +5.06.[2] Based upon an annual parallax shift of 10.88\u00a0mas as seen from Earth,[1] it is located about 300\u00a0light years from the Sun.[11] At that distance, the visual magnitude is diminished by an extinction of 0.07 due to interstellar dust. It is moving further from the Sun with a heliocentric radial velocity of +17.5\u00a0km\/s.[4]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4This is an ordinary B-type main-sequence star, as indicated by its stellar classification of B8\u00a0V.[3] It is an estimated 118[6]\u00a0million years old and is spinning with a projected rotational velocity of 98\u00a0km\/s.[6] The star has 2.7[6] times the mass of the Sun and about 3.2[7] times the Sun’s radius. It is radiating 107[5] times the Sun’s luminosity from its photoshere at an effective temperature of 11,381\u00a0K.[6] No infrared excess has been detected.[12]References[edit]^ a b c d e f van Leeuwen, F.
