17 Persei is a single[11]star in the northernconstellation ofPerseus, located about 420 light years away from the Sun. It is visible to the naked eye as a faint, orange-hued star with anapparent visual magnitude of 4.53.[2] This object is moving further from the Earth at a heliocentricradial velocity of +13 km/s.[5]

Based upon astellar classification of K5+III,[3] this is anevolvedgiant star that has exhausted the hydrogen at itscore. It is a suspectedvariable star, with an amplitude of 0.012 magnitude and period 4.4 days.[4][12] The star has 1.1 times themass of the Sun[7] and has expanded to 60 times theSun's radius. It is radiating 848 times theluminosity of the Sun from its enlargedphotosphere at aneffective temperature of 4,014 K.[8]
