HR 3082 is a double star in the northern circumpolar constellation of Camelopardalis. It is faintly visible to the naked eye with an apparent visual magnitude of 5.39.[1] The system is moving closer to the Sun with a heliocentric radial velocity of +2.7 km/s.[5] It is currently at a distance of around 341 light years, based upon an annual parallax shift of Script error: No such module "val"..[2]
The brighter component is a magnetic,[7] mild Ap star that displays an overabundance of silicon in its spectrum.[10] Cowley et al. (1969) listed a stellar classification of A0p Si,[3] while Abt and Morrell (1995) have it pegged as a subgiant star with a class of B9.5 IVs.[4] It has an estimated 2.65[6] times the mass of the Sun and 2.89[7] times the Sun's radius. The star is radiating 74[6] times the Sun's luminosity from its photosphere at an effective temperature of 10,795 K.[8]
The fainter component is a magnitude 9.6 star at an angular separation of Script error: No such module "val". along a position angle (PA) of 84°, as of 2009.[11] This is most likely a visual companion located along the same line of sight.[12] There is a magnitude 13.6 visual companion at a separation of Script error: No such module "val". along a PA of 169°, as of 2016.[11]
