V433 Aurigae is a variable star in the constellation Auriga. It is a slowly pulsating B star (SPB) that varies by a few hundredths of a magnitude over 4.6 days. It is faintly visible to the naked eye under very good observing conditions. It shines with a luminosity approximately 14,000 times that of the Sun and has a surface temperature of about 16,950 K.
V433 Aurigae was discovered to be a variable star when the Hipparcos data was analyzed. It was given its variable star designation in 1999.
