Zeta Sculptoris (ζ Scl, ζ Sculptoris) is a binary star in the constellation Sculptor. It is approximately 503 light years from Earth.[1]

The primary component, Zeta Sculptoris A, is a blue-white B-type main sequence dwarf[3] with an apparent magnitude of +5.04.[2] It has a 13th magnitude companion, Zeta Sculptoris B, 3 arcseconds distant.[9]

It is near the Blanco 1 cluster as viewed from Earth, although parallax measurements indicate it to be substantially closer.
