# HD 64484

HD 64484 (HR 3081) is a solitary star in the southern circumpolar constellation Volans. With an apparent magnitude of 5.76, it is faintly visible to the naked eye under dark skies. Parallax measurements place it at a distance of 458 light years but is receding with a heliocentric radial velocity of 11 km/s.

HD 64484 has a stellar classification of B9 V, indicating that it is an ordinary B-type main-sequence star. It has 2.8 times the mass of the Sun and an effective temperature of 10,544 K, giving it a bluish white hue. However, a slightly enlarged radius of 3.3 $R_☉$ yields a luminosity 140 times that of the Sun. This is due to HD 64484 completing 80.6% of its main sequence lifetime at an age of 339 million years. The star has a solar metallicity and like many hot stars — spins rapidly with a projected rotational velocity of 154 km/s.
