50 Camelopardalis is a double star[10] in the northern constellation of Lynx. This object is visible to the naked eye as a faint white star with an apparent visual magnitude of 5.4. It is 430 light years away and moving further from the Earth with a heliocentric radial velocity of 20 km/s.

50 Camelopardalis has a spectral classification of A0 or B9 and a luminosity class of V or III. The stellar spectrum is noted to have unusually nebulous absorption lines due to its rapid rotation. At an age of 300 million years, the star is modelled to be in the late stages of the main sequence. It has expanded to over five times the radius of the Sun and is radiating 153 times the luminosity of the Sun from its photosphere at an effective temperature of 9,974 K.[1]

Double star catalogues list an 8th-magnitude companion at a separation of 1″. Due to its closeness to the much brighter star, little is known about the companion.[10] The Tycho double star catalogue gives a proper motion similar to the bright primary star.[2]
