Star in the constellation Perseus
54 Persei is a single[ 10] star in the northernconstellation ofPerseus .It is visible to the naked eye as a faint, yellow-hued star with anapparent visual magnitude of 4.93.[ 2] light years away based onparallax ,but is drifting closer with aradial velocity of −27 km/s.[ 5]
This is an aginggiant star with astellar classification of G8+ IIIb,[ 3] core and expanded to more than nine times the girth of the Sun. It is around 580 million years old with 2.6 times themass of the Sun .The star is radiating 51 times theluminosity of the Sun from its enlargedphotosphere at aneffective temperature of 5,036 K.[ 7] visual companion ,designated component B, at anangular separation of″ [ 11]
