109 Piscium is a yellow hued G-type subgiant star located about 108 light-years away in the zodiac constellation of Pisces. It is near the lower limit of visibility to the naked eye with an apparent visual magnitude of 6.27. The star is moving closer to the Earth with a heliocentric radial velocity of −45.5 km/s. It has one known exoplanet. With a stellar classification of G3 Va, this is a Sun-like star with a similar mass but a 91% larger radius. (Cowley and Bidelman (1979) had this classified as a subgiant star that is leaving the main sequence.) It is 6.75 billion years old with a higher abundance of iron and a low projected rotational velocity of 1.3 km/s. The star is radiating 2.9 times the Sun's luminosity from its photosphere at an effective temperature of 5,442 K.
