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]
