V538 Aurigae is a star in the northern constellation of Auriga. With an apparent visual magnitude of 6.23, this star requires good dark sky conditions to view with the naked eye. It is located at a distance of 40.0 light-years (12.3 pc) from Earth.
This is a BY Draconis variable, which means it undergoes changes in luminosity because regions of pronounced surface magnetic activity are moved into and out of the line of sight from the Earth as the star rotates (once every 11 days). This has a spectral class of K1 V, indicating that it is a K-type main sequence star. It is a member of the Local Association, and is most likely a thin disk star.
