Xi2 Capricorni (ξ2 Capricorni) is a yellow-white hued star in the southern constellation of Capricornus. It is dimly visible to the naked eye on a dark night, having an apparent visual magnitude of +5.83.[2] Based upon an annual parallax shift of 36.10 mas as seen from Earth,[1] this system is located 90 light years from the Sun.
This is an F-type main-sequence star with a stellar classification of F7 V Fe−0.5,[3] where the suffix notation indicates the spectrum displays a mild underabundance of iron. It is around three billion years old with 1.2 times the mass of the Sun.[6] Although considered a single star,[8] there is reason to suspect it forms a wide physical pair with the visual magnitude 10.94[9] red dwarf star LP 754–50.[10] They have a projected separation of Script error: No such module "val"., with LP 754–50 having an estimated 0.55 times the mass of the Sun. If they are gravitationally bound, their orbital period would be around 3.7 million years.[10]
