θ Sculptoris, Latinized as Theta Sculptoris, is a star in the southern constellation of Sculptor. This object is visible to the naked eye as a dim, yellow-white hued star with an apparent visual magnitude of +5.24.[2] It is located 71 light years from the Sun based on parallax.[1] The object is drifting closer with a radial velocity of −21 km/s, and may come to within Script error: No such module "convert". in half a million years.[4]
This is an astrometric binary system.[6] The visible component is an ordinary F-type main-sequence star with a stellar classification of F5V.[3] It is around 1.6[4] billion years old with 1.25 times the mass of the Sun and 1.40 times the Sun's radius. The star is radiating three[4] times the luminosity of the Sun from its photosphere at an effective temperature of 6,395 K.[2]
