42 Camelopardalis is a single[11] star in the constellation Camelopardalis,[10] located roughly 770 light years away from the Sun.[1] It is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of 5.14.[2] The visual magnitude of the star is diminished by an extinction of 0.22 due to interstellar dust.[12] It is moving further from the Earth with a heliocentric radial velocity of 3 km/s.[4] 42 Camelopardalis has a peculiar velocity of Script error: No such module "val". and may be a runaway star.[6]
Observations made in 1933 appeared to suggest this could be a Beta Cephei variable,[13] but this was not confirmed by follow-up measurements.[14] The star has a stellar classification of B4 IV,[3] matching a B-type subgiant star. It has 6.5[6] times the mass of the Sun and about 5.6[7] times the Sun's radius. 42 Camelopardalis is 50[6] million years old with a high rotation rate, showing a projected rotational velocity of 105 km/s.[9] It is radiating 2,460[8] times the luminosity of the Sun from its photosphere at an effective temperature of 16,550 K.[8] This star is notable as demonstrating similarities between the short-period B-type variables and the Cepheid variables.Script error: No such module "Unsubst".
