SIMBAD	data

The primary component, Epsilon Sculptoris A, is a yellow-white F-type main-sequence star^[3] with an apparent magnitude of +5.29.^[2] 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.^[13]

There are two optical companions, the 15th magnitude designated Epsilon Sculptoris C at an angular separation of 15 arcseconds and the 11th magnitude Epsilon Sculptoris D, at a separation of 142 arcseconds.^[14]

This star will be in constellation Fornax around 2920 CE.^[15]
