Kappa Normae, Latinized from κ Normae, is a solitary, yellow hued star in the southern constellation of Norma. Its apparent magnitude is 4.94, 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, the system is located about 440 light years from the Sun. It is drifting closer with a radial velocity of 13.5 km/s.
This is an evolved giant star with a stellar classification of G8III that has swollen and cooled off the main sequence. At present it has 18 times the radius of the Sun. It shines with a luminosity approximately 190 times that of the Sun and has an effective temperature of 4,996 K.
