Zeta Pyxidis (ζ Pyxidis) is a wide binary star[9] system in the southern constellation of Pyxis. It is visible to the naked eye with a combined apparent visual magnitude of +4.88.[2] Based upon an annual parallax shift of 13.35 mas as seen from Earth,[1] it is located around 244 light years from the Sun. The yellow-hued primary, component A, is an evolved G-type giant star with a stellar classification of G6 IIIb CN-0.5,[4] where the suffix notation indicating it has anomalously weak lines of cyanogen. At the age of 1.88 billion years,[5] is a red clump star that is generating energy through the fusion of helium at its core.[10] The primary has nearly double the mass of the Sun and is radiating 69 times the Sun's luminosity from its photosphere at an effective temperature of 4,876 K.[5] The companion, component B, is a magnitude 9.59 star at an angular separation of 52.20 arc seconds along a position angle of 61°, as of 2010.[3] References
