Notes
This is an ordinary A-type main-sequence star with a stellar classification of A1 V,[4] which indicates it is generating energy through hydrogen fusion at its core. It is around 400[7] million years old with a relatively high rate of spin, showing a projected rotational velocity of 128 km/s.[8] The star has 2.2 times the mass of the Sun and 2.1 times the Sun's radius. It is radiating 28 times the Sun's luminosity from its photosphere at an effective temperature of 9,050 (source: Wikipedia)
