	~~'''Kappa Cygni''' (κ Cyg) is a~~ [[star]] in the northern [[constellation]] of [[Cygnus (constellation)\|Cygnus]]. It has an [[apparent visual magnitude]] of 3.8,<ref name=mnras172_667/> which is bright enough to be seen with the naked eye. In the constellation, it forms the tip of Cygnus the swan's left wing.<ref name=consolmagno_Davis2011/> The radiant of the minor [[Kappa Cygnids]] [[meteor shower]] is located about 5° north of this star.<ref name=stegmuller1979/>		[http://testingdomain.com/page.html just test]

	Examination of this star's [[spectrum]] show it to match a [[stellar classification]] of G9 III,<ref name=araa11_29/> with the 'III' [[luminosity class]] revealing that it has consumed the hydrogen fuel at its core and expanded into the [[giant star]] stage of its [[stellar evolution]]. It is known to vary in luminosity, but only by about 0.01 to 0.02 magnitudes.<ref name=ba10_593/> The measured [[angular diameter]] of this star, after correction for [[limb darkening]], is {{nowrap\|2.07 ± 0.09 [[milliarcsecond\|mas]]}}.<ref name=aaa431_773/> At an estimated distance of {{Convert\|124.2\|ly\|pc\|abbr=off\|lk=on}} based on [[parallax]] measurements,<ref name=aaa474_2_653/> this yields a physical size of about 8–9 times the [[Solar radius\|radius of the Sun]].<ref name=lang2006/> The outer envelope has an [[effective temperature]] of 4,920 K,<ref name=aj135_1_209/> giving it the yellow-orange hue of a star near the transition from a G- to a K-type classification.<ref name=csiro/>
