HD 63513 (HR 3036) is a solitary star located in the southern circumpolar constellation Volans. It has an apparent magnitude of 6.38, placing it near the max naked eye visibility. The star is situated at a distance of 634 light years but is receding with a heliocentric radial velocity of 1.4 km/s.

This object is a star with the characteristics of a G6 and G8 giant. At present it has 3.14 times the mass of the Sun but has expanded to almost 13 times the Sun's girth. It shines at 102 solar luminosities from its enlarged photosphere at an effective temperature of 5,116 K, which gives it a yellow glow. HD 63513 has an iron abundance 102% that of the Sun, placing it at solar metallicity and spins modestly with a projected rotational velocity of 1.9 km/s.
