V394 Aurigae is a semi-regular variable star in the constellation Auriga. Its brightness varies between magnitudes 6.01 and 6.11,[2] so it is faintly visible to the naked eye under ideal observing conditions. Located around 730 light-years distant, V394 Aurigae shines with a luminosity approximately 985 times that of the Sun[1] and has a surface temperature of Script error: No such module "val"..[6]

In 1991, Leroy F. Snyder discovered that the star, then called HR 2146, is a variable star.[9] It was given its variable star designation, V394 Aurigae, in 1993.[10] Koen and Eyer found that the star's brightness, as seen by Hipparcos, varies with a period of 3.9 days.[11]

It is a double star: the secondary, designated V394 Aurigae B, is an eleventh-magnitude F7V star[12] with a separation of 10 arcseconds.[13]
