V433 Aurigae is a variable star in the constellation Auriga. It is a slowly pulsating B star (SPB) that ranges from apparent magnitude 6.02 to 6.06 over 4.6 days. It is faintly visible to the naked eye under very good observing conditions. Using a Hipparcos-derived distance of about 1,060 light-years (324 pc), it shines with a luminosity approximately 322 times that of the Sun and has a surface temperature of 7400 K. However, measurements by Gaia indicate a much higher distance of 3,200 light-years (980 pc).
V433 Aurigae was discovered to be a variable star when the Hipparcos data was analyzed. It was given its variable star designation in 1999.
