Kappa Volantis, Latinized from κ Volantis, is a quadruple star system[16] in the southern constellation of Volans. The primary component has an apparent visual magnitude of 5.37, while the secondary companion is magnitude 5.65;[2] individually, both a bright enough to be faintly visible to the naked eye. Based upon parallax measurements, the stars appear to be around 420−430 light-years from the Sun.
