Star in the constellation Perseus
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 anevolved giant 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]
