Rho Piscium (ρ Piscium) is a solitary,[12] yellow-hued star in the zodiac constellation of Pisces. With an apparent visual magnitude of +5.34,[2] it is faintly visible to the naked eye. Based upon an annual parallax shift of 39.66 mas as seen from Earth,[1] it is located 82 light years from the Sun. It is a member of the thin disk population of the Milky Way.[9]
This is an F-type main sequence star with a stellar classification of F2 V.[3] It is a suspected variable star that ranges in magnitude from a maximum of 5.35 to a minimum of 5.44 magnitude.[13] The star is a source of X-ray emission with a luminosity of 117.6×1020 W.[14] It is 778[6] million years old and is spinning with a projected rotational velocity of 60.1 km/s.[10] The star has 1.3[6] times the mass of the Sun and about 1.1[7] times the Sun's radius. It is radiating 3.6[8] times the Sun's luminosity from its photosphere at an effective temperature of 6,822 K.[6]
