Lambda Pegasi
Lambda Pegasi (λ Peg, λ Pegasi) is a fourth-magnitude star in the constellation Pegasus.
λ Pegasi is a yellow giant with stellar classification G8II-III. With a mass of 1.5 M☉ and radius that is 28.5 R☉, the star boasts a bolometric luminosity that is roughly 390 L☉. Its apparent magnitude was calibrated in 1983 at 3.96, yielding an absolute magnitude of -1.45. Parallax calculations place the star at a distance of roughly 112 parsecs from Earth, or 365 ± 10 light years away, about three times the distance of its line-of-sight double μ Pegasi.
In the constellation, Lambda and Mu lie to the southwest of Beta Pegasi, the nearest bright star.
