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. Koen and Eyer found that the star's brightness, as seen by Hipparcos, varies with a period of 3.9 days.[6] Located around 730 light-years distant, V394 Aurigae shines with a luminosity approximately 1075 times that of the Sun and has a surface temperature of 3589 K.[4]
It is a double star: the secondary, designated V394 Aurigae B, is an eleventh-magnitude star with a separation of 10 arcseconds.[7]
