Star in the constellation Perseus
59 Persei is a suspected astrometric binary [ 8] star system in the northern constellation of Perseus . It is visible to the naked eye as a dim, white-hued star with an apparent magnitude of 5.30.[ 2] light years distant from the Sun, based on parallax ,[ 1] radial velocity of +13 km/s.[ 2]
This is an ordinary A-type main-sequence star with a stellar classification of A1Vn,[ 4] hydrogen . The 'n' suffix indicates "nebulous" lines due to rapid spin; it has a projected rotational velocity of 212 km/s.[ 3] [ 5] [ 5] mass of the Sun and about 2.5[ 6] Sun's radius . It is radiating 41[ 3] luminosity of the Sun from its photosphere at an effective temperature of 10,734 K.[ 5]
