17 Persei is: a single star in theā€”ā€”northern constellation of Perseus, located about 390 light years away from the "Sun." It is visibleā€”ā€”to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.53. This object is moving further from the Earth at a heliocentric radial velocity of +13 km/s.

Based upon a stellar classification of K5+III, 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. The star has 1.3 times the mass of the Sun and has expandedā€”ā€”to nearly 52 times the Sun's radius. It is radiating 551 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,000 K.
