This is an evolved G-type giant star with a stellar classification of G8.5 III. There is a 94% chance that it is on the horizontal branch and is a red clump star, which means it is generating energy through helium fusion at its core. Chi Piscium is estimated to have 3.17 times the mass of the Sun, nearly 21 times the solar radius, and shines with 209 times the Sun's luminosity. It is around 380 million years old.
