23 Camelopardalis is a star in the northern circumpolar constellation of Camelopardalis, located 433 light years away from the Sun.[1] It is just visible to the naked eye as a dim, yellow-hued star with an apparent visual magnitude of 6.17.[2] The object is moving closer to the Sun with a heliocentric radial velocity of −2.5 km/s.[1]

With a stellar classification of G5 III:,[2] 23 Camelopardalis appears to be an aging giant star that has exhausted the hydrogen at its core and evolved away from the main sequence, although the ':' denotes some uncertainty about the classification. It is a red clump giant,[3] which indicates it is on the horizontal branch and is generating energy through helium fusion at its core. The star is 1.5[2] billion years old with more than double[2] the mass of the Sun and almost 10[1] times the Sun's radius. It is radiating 60[1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 5,183 K.[4]
