Lambda Piscium (λ Psc) is a star approximately 101 light years away from Earth in the constellation Pisces. It is a bluish-white star of A7V spectral classification, meaning it has a surface temperature of 7,500 to 11,000 kelvins. It is much brighter and hotter in surface temperature than our sun, yet is approximately the same size.[2] Lambda Piscium forms the southeast corner of the "Circlet" in Pisces.[3]
