Kappa Persei or κ Persei, is a triple star system in the northern constellation of Perseus. Based upon an annual parallax shift of 28.93 mas,[1] it is located at a distance of 113 light-years from the Sun.
The system consists of a spectroscopic binary,[8][5] designated Kappa Persei A, which can be seen with the naked eye, having an apparent visual magnitude of 3.80.[2] The third star, designated Kappa Persei B, is of magnitude 13.50.[9]
Kappa Persei A's two components are designated Kappa Persei Aa (officially named Misam /ˈmaɪzəm/, the traditional name of the entire system)[10] and Ab.
