SIMBAD data

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]
