107 Piscium (abbreviated 107 Psc) is a K-type main sequence star in the constellation of Pisces, about 24.4 light years away from the Earth. 107 Piscium is the Flamsteed designation. It has an apparent visual magnitude which varies between 5.14 and 5.26.
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.
The star is somewhat older than the Sun—approximately 6 billion years old. It has 83% of the mass and 80% of the radius of the Sun, but shines with only 46% of the Sun's luminosity. The effective temperature of the star is 5,242 K. It is rotating slowly with a period of 35.0 days. The abundance of elements other than hydrogen and helium—the star's metallicity—is slightly lower than that of the Sun.
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 0.52–1.10 Astronomical Units (AU), where 1 AU is the average distance from the Earth to the Sun.
