Ν_Pegasi
Nu Pegasi
Star in the constellation Pegasus
ν Pegasi, Latinized as Nu Pegasi is a single[12] star in the northern constellation of Pegasus. It is an orange-hued star that is faintly visible to the naked eye with an apparent visual magnitude of 4.84.[2] The star is located approximately 261 light years away based on parallax,[7] but is drifting closer with a radial velocity of −19 km/s.[6]
This is an aging giant star, most likely (94% chance) on the red giant branch,[3] with a stellar classification of K4III.[4] It is a suspected variable, with a magnitude range observed from 4.83 to 4.86.[5] With the supply of hydrogen at its core exhausted, the star has cooled and expanded to 24.6 times the Sun's radius. It is 13% more massive than the Sun and is radiating 149 times the Sun's luminosity from its swollen photosphere at an effective temperature of 4,073 K.[9]
