Nu Persei

April 22, 2024

ν Persei, Latinized as Nu Persei, is a single[13] star and a suspected variable in the northern constellation of Perseus. It has a yellow-white hue and is visible to the naked eye with an apparent visual magnitude of 3.80.[2] This object is located approximately 560 light-years from the Sun based on parallax[1] but is drifting closer with a radial velocity of −12 km/s.[5]

This object is a highly luminous bright giant star with a stellar classification of F5II.[3] It has five[7] times the mass of the Sun but has expanded to around 21[8] times the Sun's radius. The star has a relatively high rotation rate, spinning with a projected rotational velocity of 48.9 km/s.[10] It is radiating 604[8] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 6,300 K.[8]

Several visual companions beside the primary have been recorded. B, with magnitude 12.1 and separation 31.6", has its own companion, E, with magnitude 14.3 and separation 7.7". Additionally, C has magnitude 13.2 and separation 55.7", and D has magnitude 13.8 and separation 22.8".[14]
