Delta Sculptoris (δ Scl, δ Sculptoris) is a triple star system [9] in the constellation Sculptor. It is approximately 137.4 light years from Earth. [1]
The primary component, Delta Sculptoris A, is a white A-type main sequence dwarf [3] with an apparent magnitude of +4.59. It has a faint, 11.6 magnitude companion, Delta Sculptoris B, 4 arcseconds, or more than 175 astronomical units, away from it. Orbiting this pair at the much greater separation of 74 arcseconds, is the yellow G-type Delta Sculptoris C, which has an apparent magnitude of +9.4. [9] [10]
This system is a candidate member of the AB Doradus moving group, an association of stars with similar ages that share a common heading through space. [11]
