42 Camelopardalis is a single star in the … 42 Camelopardalis is a single star in the constellation Camelopardalis, located roughly 770 light years away from the Sun. It is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of 5.14. The visual magnitude of the star is diminished by an extinction of 0.22 due to interstellar dust. It is moving further from the Earth with a heliocentric radial velocity of 3 km/s. 42 Camelopardalis has a peculiar velocity of 24.4+1.9−2.1 km/s and may be a runaway star. Observations made in 1933 appeared to suggest this could be a Beta Cephei variable, but this was not confirmed by follow-up measurements. The star has a stellar classification of B4 IV, matching a B-type subgiant star. It has 6.5 times the mass of the Sun and about 5.6 times the Sun's radius. 42 Camelopardalis is 50 million years old with a high rotation rate, showing a projected rotational velocity of 105 km/s. It is radiating 2,460 times the luminosity of the Sun from its photosphere at an effective temperature of 16,550 K. This star is notable as demonstrating similarities between the short-period B-type variables and the Cepheid variables.-type variables and the Cepheid variables.

Den har en skenbar magnitud på ca 5,14 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 4,2 mas, beräknas den befinna sig på ett avstånd på ca 770 ljusår (ca 240 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 3 km/s. och kan med en egenrörelse av 24,4 +1,9−2,1 km/s vara en flyktstjärna. På det beräknade avståndet minskar stjärnans skenbara magnitud med 0,22 enheter genom en skymningsfaktor orsakad av interstellärt stoft.ingsfaktor orsakad av interstellärt stoft.
