Kappa Volantis, Latinized from κ Volantis, is a quadruple star system 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; 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.
Properties
The brightest component, κ1 Volantis, is a blue-white B-type star with a stellar classification showing characteristics of a both a subgiant and giant star. It has an unseen companion, and the pair form a single-lined spectroscopic binary. The star has nearly three times the Sun's mass, and 3.8 times its radius. It radiates at 129 times the Sun's luminosity from its photosphere at an effective temperature of {{val|9884|ul=K|fmt=commas}}.
Companion
Separated from κ1 Volantis by 65 arcseconds, κ2 Volantis is a white subgiant star that falls between a B-type and A-type classification. The system's fourth component, κ Volantis C, is a magnitude +8.5 star 37.7 arcseconds away from κ2 Volantis.
