40 Camelopardalis is a single[7] star in the northern circumpolar constellation of Camelopardalis,[6] located around 600 light years distant from the Sun.[1] It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 5.37.[2] This object is moving further from the Earth with a heliocentric radial velocity of +8.6 km/s.[4]
This is an aging giant star with a stellar classification of K3 III,[3] having exhausted the hydrogen at its core and evolved away from the main sequence. It has expanded to 39[1] times the Sun's radius and is radiating 424[1] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,188 K.[1]
There is a magnitude 11.50 optical companion, located at an angular separation of 104.20″ along a position angle of 355° from 40 Camelopardalis, as of 2010.[8]
