2 Camelopardalis is a triple star[6] system in the northern circumpolar constellation of Camelopardalis, next to the southern constellation border with Perseus. It is dimly visible to the naked eye with a combined apparent visual magnitude of 5.36.[2] The system is located at a distance of about Script error: No such module "convert". from the Sun, based on its parallax.[1] It is drifting further away with a radial velocity of +20 km/s.[4]
The primary member of 2 Camelopardalis, designated component A, is an A-type main-sequence star with a spectral type of A8V. It has an apparent magnitude of 5.86, and has a secondary with an apparent magnitude of 7.35, designated component B.[7] The two orbit each other on a very eccentric orbit with a period of 26.34 years.[5] Further out, there is an eight-magnitude companion (designated component C), orbiting once every few hundred years.[5] As the third star was previously thought to be relatively massive for its luminosity, it was suspected of being a binary star itself,[8] but the current estimate of component C's magnitude as a single star matches its absolute magnitude.[5]
