MWC 480 is a single[4] star, about 500 light-years away in the constellation of Auriga. It is located in the Taurus-Auriga Star-Forming Region.[8] The name refers to the Mount Wilson Catalog of B and A stars with bright hydrogen lines in their spectra.[9] With an apparent magnitude of 7.62,[3] it is too faint to be seen with the naked eye.
