17 Camelopardalis is a single[9] star in the northern circumpolar constellation of Camelopardalis, located roughly 960 light years away from the Sun. It is visible to the naked eye as a faint, red-hued star with an apparent visual magnitude of 5.44. This object is moving closer to the Earth with a heliocentric radial velocity of −20 km/s.
This is an ageing red giant star, currently on the asymptotic giant branch,[3] with a stellar classification of M1IIIa.[4] It is a suspected small amplitude variable.[2] The star has expanded to 100 times the Sun's radius and is radiating 3,230 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of Script error: No such module "val"..
