36 Camelopardalis

36 Camelopardalis is a single star[11] in the northern circumpolar constellation of Camelopardalis. It is visible to the naked eye as a dim point of light with an apparent visual magnitude of +5.3. Parallax measurements provide a distance estimate of approximately 710 light years away from the Sun, and it is drifting away from the Earth with a radial velocity of −1.15 km/s.

36 Camelopardalis has a stellar classification of K1 III-IIIb, which indicates that it is a K-type giant star with a mild underabundance of CH molecules in its spectrum. At present it has 1.24 times the mass of the Sun but has expanded to an enlarged diameter of 42 R. It shines at 714 L from its photosphere at an effective temperature of 4,589 K, giving it an orange glow. 36 Cam's metallicity is around solar level and spins slowly with a projected rotational velocity of 3 km/s.
