Kappa Piscium is notable as being a variablestar, belonging to the class known as Alpha2 Canum Venaticorumvariables. Variations in the star's intense magnetic field cause heavy metals (particularly strontium) to distribute itself unevenly on the star's surface layers, causing its luminosity to apparently vary as it rotates on its axis. This patterning means that it is possible to measure how quickly Kappa Piscium rotates: it takes some forty-eight hours to complete one rotation (that is, the star rotates nearly thirteen times faster than the Sun).
Kappa Piscium is one of the brighter members of a loosely connected group of about a hundred stars known collectively as the AB Doradus Moving Group. Thought to share a common origin about four hundred million years ago, these stars are now widely spread across the sky. Most are extremely faint as seen from Earth, but other prominent members of the same group include Rukbat in Sagittarius and Alnair in Grus.
