PU Aurigae is an irregular variable star located in the constellation Auriga. A red giant, it varies by 0.1 magnitude around magnitude 5.64,[8] so it is faintly visible to the naked eye. Located around 560 light-years distant, it shines with a luminosity approximately 1,523 times that of the Sun and has a surface temperature of 3,482 K.[6]

Although the star was first found to be variable by Joel Stebbins and Charles Morse Huffer in 1928,[9] it was not given its variable star designation until 1977.[10]
