101 Piscium is a star in the zodiac constellation of Pisces,[9] located around 1,400 light years away from the Sun. This appears as a dim, blue-white hued star near the lower limit of visibility to the naked eye at an apparent visual magnitude of 6.23.[2] It is a suspected variable star with the designation NSV 559;[10] 101 Piscium is the Flamsteed designation. The star is moving closer to the Earth with a heliocentric radial velocity of −10 km/s.[5]
This object has a stellar classification of B9.5 III,[3] matching a giant star that has consumed the hydrogen at its core and is evolving away from the main sequence.[6] It is spinning rapidly with a projected rotational velocity of 246[6] km/s, compared to a critical velocity of 270 km/s.[8] The star has 4.5[6] times the mass of the Sun and about 3.6[7] times the Sun's radius. It is radiating around 1,000[6] times the luminosity of the Sun from its photosphere at an effective temperature of 10,471 K.[6]
