ζ Pictoris, Latinised as Zeta Pictoris, is a solitary[16] star in the southern constellation of Pictor. It is visible to the naked eye with an apparent visual magnitude of +5.43.[3] Based upon an annual parallax shift of 28.00 mas as seen from the Earth, 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.[4] It is a thin disk[20] star with an estimated 1.4[12] times the mass of the Sun and about 5.3[13] times the Sun's radius. At the age of 2.6[12] billion years, Zeta Pictoris is spinning with a projected rotational velocity of 5.6 km/s.[14]
