Star in the constellation Perseus
17 Persei is a single[ 13] star in the northern constellation of Perseus , located about 390 light years away from the Sun. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.53.[ 2] This object is moving further from the Earth at a heliocentric radial velocity of +13 km/s.[ 5]
Based upon a stellar classification of K5+III,[ 3] this is an evolved giant star that has exhausted the hydrogen at its core . It is a suspected variable star , with an amplitude of 0.012 magnitude and period 4.4 days.[ 4] [ 14] The star has 1.3[ 8] times the mass of the Sun and has expanded to nearly 52[ 1] times the Sun's radius . It is radiating 551[ 1] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,000 K.[ 10]
