30 Camelopardalis is a star in the northern circumpolar constellation of Camelopardalis,[5] located about 539 light years away from the Sun based on parallax.[1] It can be viewed with the naked eye in good seeing conditions, appearing as a dim, white-hued point of light with an apparent visual magnitude of 6.14.[2] This is most likely a slowly rotating[6] A-type main-sequence star with a stellar classification of A0Vs,[3] which indicates it is generating energy via hydrogen fusion at its core. It is moving further from the Earth with a heliocentric radial velocity of +12 km/s.[2]
