Kappa Pictoris
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. Based upon an annual parallax shift of 5.14 mas as seen from Earth, 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.
