Star in the constellation Auriga
64 Aurigae is a single[7] star located 312[1] light years away from the Sun in the northern constellation of Auriga.[6] It is visible to the naked eye as a dim, white-hued star with an apparent magnitude of 5.87.[2] The star is moving closer to the Earth with a heliocentric radial velocity of −10, and may come to within 167 light-years in around 5.3 million years.[2] It is a member of the Sirius supercluster.[8]
This object is an ordinary A-type main-sequence star with a stellar classification of 5 Vn,[4] where the 'n' notation is used to indicate "nebulous" lines in the spectrum caused by rapid rotation. It is 291[5] million years old with a projected rotational velocity of 212 km/s.[3] The star has 1.67[5] times the mass of the Sun and is radiating 27[2] times the Sun's luminosity from its photosphere at an effective temperature of 8,014 K.[5]
It was also known to be part of a much bigger constellation named Telescopium Herschelii before it was unrecognized by the International Astronomical Union (IAU).
