Episolon Piscium (ε Psc) is a star approximately 190 light years away from the Earth, in the constellation Pisces. It is a yellow-orange star of the G9III or K0III spectral type, meaning it has a surface temperature around 5,000 kelvins. It is a normal giant star, slightly cooler in surface temperature, yet brighter and larger than our Sun.[2] It is a suspected occulation double, with both stars having the same magnitude, separated by 0.25 arcsecond.[3]
