107 Piscium is a singlestar in the constellation of Pisces. 107 Piscium is the star's Flamsteed designation. John Flamsteed numbered the stars of Pisces from 1 to 113, publishing his Catalogus Britannicus in 1725. He accidentally numbered 107 Piscium twice, as he also allocated it the designation of 2 Arietis. This star is faintly visible to the naked eye with an apparent visual magnitude that has been measured varying between 5.14 and 5.26. However, that finding of variation was not confirmed by subsequent observations and is most likely spurious data. It is located at a distance of about away from the Sun. 107 Piscium is drifting closer to the Sun with a radial velocity of -33.6, and is predicted to come as close as 15.4 light-years in around 135,800 years.
107 Piscium has been examined for the presence of an infrared excess caused by exozodiacal dust, but none was detected. The habitable zone for this star, defined as the locations where liquid water could be present on an Earth-like planet, is at a radius of 0.52- (AU), where is the average distance from the Earth to the Sun.
In 1997, based on data collected during the Hipparcos mission, the star was categorized as an astrometric binary with a period of . However, this result has not been not confirmed.
