Kappa Normae, Latinized from κ Normae, is a solitary,[7] yellow hued star in the southern constellation of Norma. Its apparent magnitude is 4.94,[2] which is bright enough to be faintly visible to the naked eye. Based upon an annual parallax shift of 7.44 mas as seen from Earth,[8] the system is located about 440 light years from the Sun. It is drifting closer with a radial velocity of 13.5 km/s.[4]
This is an evolved giant star with a stellar classification of G8III[3] that has swollen and cooled off the main sequence. At present it has 22[1] times the radius of the Sun. It shines with a luminosity approximately 226 times that of the Sun and has an effective temperature of 4,787 K.[1]
