17 Camelopardalis is a single[8] star in the northern circumpolar constellationofCamelopardalis, 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,[9] with a stellar classification of M1IIIa.[3] 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 temperatureof3,852 K.
