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).
