HD 60150 (HR 2888) is a solitary star located in the constellation Volans. With an apparent magnitude of 6.39, it is close to the limiting magnitude for naked-eye visibility. The star is located 754 light years away from the Solar System, but is drifting away with a radial velocity of 14.14 km/s.

Properties[]

HD 60150 has a classification of "K5III", which means it is a K-type star that has exhausted the hydrogen at its core, and left the main sequence. It has 1.56 times the mass of the Sun, but has expanded to 36.77 the Sun's girth. It radiates 329 times the Sun's luminosity from its swollen photosphere at an effective temperature of 4,055 K, which gives it a yellow-orange hue. HD 60150 is metal-rich, with 12% more heavy metals than the Sun, and has a projected rotational velocity of 1.8 km/s.
