51 Camelopardalis (51 Cam), also designated as HD 62066, is a solitary star located in the northern circumpolar constellation Camelopardalis. It is faintly visible to the naked eye as an orange-hued point of light with an apparent magnitude of 5.93.[2] Gaia DR3 parallax measurements imply a distance of 334 light-years[1] and it is currently receding with a heliocentric radial velocity of −30.9 km/s.[5] At its current distance, 51 Cam's brightness is diminished by 0.17 magnitudes due to interstellar extinction[13] and it has an absolute magnitude of +0.92.[6]
51 Cam has a stellar classification of K2 III,[3] indicating that it is an evolved K-type giant star. It has a comparable mass to the Sun[7] but it has more than twice the latter's age at 9.25 billion years.[7] As a result, it has exhausted hydrogen at its core and it has expanded to 11.8 times the radius of the Sun.[8] It radiates 57.2 times the luminosity of the Sun[8] from its enlarged photosphere at an effective temperature of 4,626 K.[10] 51 Cam has a solar metallicity at [Fe/H] = +0.00.[11]
