37 Camelopardalis has a stellar classification of G8 III,[3] indicating that the object is an ageing yellow giant. It has an angular diameter of 1.36±0.02 mas,[12] with an actual size of 19.3 R☉.[8] At present it has 1.43 times the mass of the Sun and shines at 129 times the luminosity of the Sun from its photosphere at an effective temperature of 4,609 K,[7] giving it a yellow orange glow. 37 Cam is a metal poor star with an iron abundance only 32% that of the Sun[9] and spins modestly with a projected rotational velocity of 1.5 km/s.[10]
