Variable star in the constellation Auriga
Nu Aurigae ,
Latinised from ν Aurigae, is the
Bayer designation for a
star in the
northern
constellation of
Auriga . It is visible to the naked eye with an
apparent visual magnitude of 3.96
[2] and is approximately 220
light-years (67
parsecs ) distant from the Earth. This is an
evolved
giant star with a
stellar classification of G9.5 III.
[8] It is a
red clump star, which indicates that it is generating energy through the
fusion of
helium at its core.
[9] The
outer envelope has expanded to 19 times the
radius of the Sun and cooled to K
[4] giving it the characteristic yellow-hued glow of a
G-type star . It shines with 135 times the
luminosity of the Sun .
[4]
This is an
astrometric binary with a suspected
white dwarf companion.
[3] A 10th-magnitude star 54.6
arcseconds away is an
optical companion .
