HD 29559 is a solitary star located in the constellation Caelum. With an apparent magnitude of 6.41, it’s near the limit of naked eye visibility. The star is located 407 light years away from the Solar System based on parallax, but is drifting away with a radial velocity of 24.2 km/s

Properties[]

HD 29559 has a class of “A3V(s)”, which means it’s a main sequence star with “sharp” absorption lines. It has 1.87 times the Sun’s mass, but has 3.173 times the Sun’s radius. It radiates at 34 solar luminosities, and has an effective temperature of 7,852 K, which gives it a white hue. HD 29559 is a rapid rotator, with a projected rotational velocity of 179 km/s. HD 29559 is slightly metal-deficient, with 87% the abundance of heavy metals compared to the Sun.
