Variable star in the constellation Auriga
Nu Aurigae ,Latinised from ν Aurigae, is theBayer designation for astar in thenorthern constellation ofAuriga . It is visible to the naked eye with anapparent visual magnitude of 3.96[ 2] and is approximately 200light-years (61parsecs ) distant from the Earth.[ 1] This is anevolved giant star with astellar classification of G9.5 III.[ 9] It is ared clump star, which indicates that it is generating energy through thefusion ofhelium at its core.[ 10] Theouter envelope has expanded to 18 times theradius of the Sun and cooled to 4,576 K ,[ 7] giving it the characteristic yellow-hued glow of aG-type star .[ 11] It shines with 126 times theluminosity of the Sun .[ 7]
This is anastrometric binary with a suspectedwhite dwarf companion.[ 3] A 10th-magnitude star 54.6arcseconds away is anoptical companion .
