17 Persei is a single[11] star in the northern constellation of Perseus, located about 420 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][12] The star has 1.1 times the mass of the Sun[7] and has expanded to 60 times the Sun's radius. It is radiating 848 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,014 K.[8]
