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.
