HD 30442

HD 30442 (HR 1527) is a solitary star in the northern circumpolar constellation Camelopardalis. It is faintly visible to the naked eye with an apparent magnitude of 5.47 and is estimated to be 403 light years away from the Solar System. The object has a heliocentric radial velocity of −37 km/s, indicating that it is drifting closer.

HD 30442 has a stellar classification of M3 IIIab, indicating that it is a red giant. It is an asymptotic giant branch star currently generating energy using hydrogen and helium shells around an inert carbon core. It has 109% the mass of the Sun and has an enlarged radius of 70.8 R due to its evolved state. It radiates at almost 1,100 times the luminosity of the Sun from its photosphere at an effective temperature of 3,500 K, giving a red hue. HD 30442 is estimated to have a solar metallicity, with an abundance of iron equivalent to that of the Sun.

HD 30442 has a companion 120 away along a position angle of 350°. It shares a common proper motion with HD 30442, suggesting physical relation, but its parallax indicates otherwise.
