Epsilon Sculptoris (ε Scl, ε Sculptoris) is a star system in the constellation Sculptor. It is approximately 89.5 light years from Earth. The primary component, Epsilon Sculptoris A, is a yellow-white F-type subgiant with an apparent magnitude of +5.29 with an angular diameter of 000509 arcseconds. Orbiting it with a separation of 4.6 arcseconds, or at least 125 Astronomical Units, is Epsilon Sculptoris B, a yellow G-type main sequence dwarf with an apparent magnitude of +8.6. A and B make one orbit around their centre of mass once every 1200 years. They are accompanied by two more distant and dimmer companions, the 15th magnitude Epsilon Sculptoris C at a separation of 15 arcseconds and the 11th magnitude Epsilon Sculptoris D, at a separation of 142 arcseconds. ε Scl A Solar radius = 1.5. ref. Solar luminosity = 5.0. ref.
