ζ Pictoris, Latinised as Zeta Pictoris, is a solitary [10] star in the southern constellation of Pictor. It is visible to the naked eye with an apparent visual magnitude of +5.43. [2] Based upon an annual parallax shift of 28.00 mas as seen from the Earth, [1] the system is located 116.5 light years from the Sun.
This is an evolving F-type subgiant star with a stellar classification of F6 IV. [3] It is a thin disk [11] star with an estimated 1.4 [6] times the mass of the Sun and about 5.3 [7] times the Sun's radius. At the age of 2.6 [6] billion years, Zeta Pictoris is spinning with a projected rotational velocity of 5.6 km/s. [8]
