Lambda Piscis Austrini,
light years from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.16 due to interstellar dust.[5]
This is a
projected rotational velocity of 50 km/s[8] and is 76% of the way through its main sequence lifetime. It is radiating 249 times the solar luminosity from its photosphere at an effective temperature of 12,023 K.[6]
Lambda Piscis Austrini is moving through the Galaxy at a speed of 18.1 km/s relative to the Sun. Its projected Galactic orbit carries it between 23,800 and 29,300 light years from the center of the Galaxy.[11]
Naming
In
Chinese name for λ Piscis Austrini itself is 羽林軍六 (Yǔ Lín Jūn liù, English: the Sixth Star of Palace Guard.)[12]
