}}{{Starbox end}}Kappa Arae (κ Ara, κ Arae) is the Bayer designation for a single[16] star in the southern constellation of Ara. Based upon parallax measurements, it is approximately {{Convert|460|ly|pc|abbr=off|lk=on}} distant from Earth, give or take a 30 light-year margin of error.[ With an apparent visual magnitude of 5.21,[3] this star is faintly visible to the naked eye.]
This is a giant star with a stellar classification of G8 III;[4] its outer envelope has expanded to about 14 times the radius of the Sun.[11] It is radiating energy into space at an effective temperature of 4,950 K.[10] This is hot enough for it to shine with the golden-hued glow of a G-type star.[22]
It has two 14th magnitude optical companions that are at an angular distance of 25 and 30 arcseconds.{{citation needed|date=July 2012}}
