Kappa Reticuli (κ Reticuli) is a binary star^[3] system in the southern constellation of Reticulum. It is visible to the naked eye, having a combined apparent visual magnitude of +4.71.^[2] Based upon an annual parallax shift of 45.91 mas as seen from Earth,^[1] it is located at a distance of 71 light-years. Based upon its space velocity components, this star is a member of the Hyades supercluster of stars that share a common motion through space.^[11]

Houk and Cowley (1978) catalogued the yellow-hued^[12] primary, component A, with a stellar classification of F3 IV/V,^[5] indicating this is an F-type star that showing mixed traits of a main-sequence and a more evolved subgiant star. Later, Grey et al. (2006) listed a class of F3 V,^[4] suggesting it is an F-type main-sequence star. It is emitting a statistically significant amount of infrared excess, suggesting the presence of an orbiting debris disk.^[13] The secondary, component B, is an orange-hued^[12] star with a visual magnitude of 10.4 at an angular separation of 54 arcseconds from the primary.^[3]

Notes

^ Calculated using absolute bolometric magnitude of +2.95±0.05 via the equation 10^{0.4(4.74−M_bol)}.
