29 Camelopardalis (29 Cam) is a double star in the circumpolar constellation Camelopardalis. With an apparent magnitude of 6.59,[1] 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[2] away based on parallax, but is drifting further away with a radial velocity of 3.9 km/s.[3]

29 Cam A

29 Cam A has a classification of A4IV-V, which suggests that this star is beginning to evolve off the main sequence. Zorec et al. models it as a star that has completed 90.6% of the main sequence, which correlates to an age of 380 million years.[4] At present, 29 Cam has 2.47 the mass of the Sun,[4] and 3.49 times its radius. [5] It radiates at 58.9 times the luminosity of the Sun from an effective temperature of 8,337 K,[4] which gives it a white hue of an A-type star. 29 Cam spins rapidly at a projected rotational velocity of 123 km/s despite its evolved state.

29 Cam B

29 Cam has a companion designated BD+56 1065B, which is a 10 magnitude star. According to the proper motion, this star is unrelated to the primary, and is 4 times farther than the primary.[6] The companion is relatively cooler and less luminous than the primary.
