Xi Sculptoris, Latinized from ξ Sculptoris, is a solitary^[6] orange-hued star in the southern constellation of Sculptor, near the southern constellation boundary with Phoenix. It is just visible to the naked eye as a dim point of light with an apparent visual magnitude of 5.59.^[2] The distance to Xi Sculptoris is approximately 489 light years based on parallax, while it is drifting closer with a radial velocity of −31 km/s.^[4] It has an absolute magnitude of −0.39.^[2]

This object is an aging giant star with a stellar classification of K1 III,^[3] which indicates it has exhausted the supply of hydrogen at its core then expanded and cooled off the main sequence. At present it has 22^[1] times the girth of the Sun. It is radiating 182 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,489 K.^[1]
