HD 33266 (HR 1675) is a solitary star in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 6.17, making it faintly visible to the naked eye. Located 481 light years away, it is approaching the Sun with a heliocentric radial velocity of −4.4 km/s.

HD 33266 is an A-type star with 2.45 times the mass of the Sun and 3.14 times the radius of the Sun. It shines at 49.7 L_☉ from its photosphere at an effective temperature of 8,952 K, giving it a white glow. Due to HD 33266 being an Am star, it spins slowly with a projected rotational velocity of 15 km/s at an age of 340 million years. Its metallicity − elements heavier than helium − is at solar level.

Note

1. Despite it being referenced as either A2 III or IV, this is actually an Am main sequence star.
