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]
