29 Camelopardalis (29 Cam) is a double star in the circumpolar constellation Camelopardalis. With an apparent magnitude of 6.59,[2] it's right below the max visibility to the naked eye, and can only be viewed under phenomenal conditions. The star is located 484 light years[1] away based on parallax, but is drifting further away with a radial velocity of 3.9 km/s.[3]
