HD 63513 (HR 3036) is a solitary star in the southern circumpolar constellation Volans. With an apparent magnitude of 6.38, it's barely visible to the naked eye under ideal conditions. The star is located 636 light-years (195 parsecs) away based on parallax, but is drifting farther with a heliocentric radial velocity of 2.23 km/s.

Properties[]

HD 63513 has a classification of G6/G8III, which means it's a giant star with the characteristics of a G6 star and a G8 star. It has 2.38 times the Sun's mass, but has expanded to 13.9 times the Sun's girth. It radiates at 110 times the Sun's luminosity from it's enlarged photosphere at an effective temperature of 5,018 K. In terms of metallicity, HD 63513's iron content is similar to the Sun's, and rotates slowly like many giants.
