HD 63584 (HR 3038) is a solitary star in the southern circumpolar constellation Volans. With an apparent magnitude of 6.15,[2] it is barely visible to the naked eye under ideal conditions. The star is located 420 light years[1] away based on parallax, but is drifting away with a radial velocity of 10.4 km/s.[5]

HD 63584 has a classification of "A0 IV/V",[3] which states it is an A0 star with the characteristics of a main sequence and subgiant star. It has 2.58 times the Sun's mass,[7] but a radius around 3 times that of the Sun.[8] HD 63584 radiates at 60 times the Sun's luminosity[7] from its photosphere at an effective temperature of 9,954 K,[7] which gives it the blueish-white hue of an A0 star. Despite the "IV" part of the classification, HD 63584 is only 256 million years old,[7] having completed only 59.6% of its main sequence lifetime.[7]
