κ Pictoris, Latinised as Kappa Pictoris, is a star in the constellation Pictor. It is close to the lower limit of stars that are visible to the naked eye having an apparent visual magnitude of +6.11.[2] Based upon an annual parallax shift of 5.14 mas as seen from Earth,[1] this star is located around 630 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.10 due to interstellar dust.[5]
This is a B-type main sequence star with a stellar classification of B8/9 V.[3] It is about 76.4% of the way through its main sequence lifespan.[6] The star is spinning rapidly with a projected rotational velocity of 264 km/s.[6] It has an estimated 3.4 times the mass of the Sun and is radiating 210 times the Sun's luminosity from its photosphere at an effective temperature of 11,641 K.[6]
