This object is a star with the characteristics of a G6 and G8 giant.[3] At present it has 3.14 times the mass of the Sun but has expanded to almost 13 times the Sun's girth.[7] It shines at 102 solar luminosities from its enlarged photosphere at an effective temperature of 5,116 K,[7] which gives it a yellow glow. HD 63513 has an iron abundance 102% that of the Sun,[7] placing it at solar metallicity and spins modestly with a projected rotational velocity of 1.9 km/s.[8]
