Epsilon Piscium (Epsilon Psc, ε Piscium, ε Psc) is the Bayer designation for a star approximately 182 light-years (56 parsecs) away from the Earth,[2] in the constellation Pisces. It is a yellow-orange star of the G9 III or K0 III spectral type. This is a giant star, slightly cooler in surface temperature, yet brighter and larger than the Sun.[5] It is a suspected occultation double, with both stars having the same magnitude, separated by 0.25 arcsecond.[8]
