Omega piscium
Omega Piscium (Omega Psc, ω Piscium, ω Psc) is a star approximately 106 light years away from Earth, in the constellation Pisces. It has a spectral type of F4IV, meaning it is a subgiant/dwarf star, and it has a temperature of 6,600 kelvins. It may or may not be a close binary star system. Variations in its spectrum were once interpreted as giving it an orbital period of 2.16 days, but this claim was later debunked as false. It is 20 times brighter than the Sun and is 1.8 times greater in mass, if it is a single star.

Counting stars with Flamsteed numbers, Greek letters, and proper names, Omega Piscium was the named star with the highest right ascension (akin to terrestrial longitude). Due to the 26,000-year wobble of the Earth's axis, this changed in 2013, when its right ascension was reset to 0 hours. It is the first star to the east of the Circlet of Pisces, which represents the head of the western fish in the constellation.
