VV Cephei A is one of the largest known stars, being a red supergiant. Its diameter is 1,475 times that of the Sun. It is orbited by VV Cephei B, a blue star with 13–25 times the Solar radius. If VV Cephei A were placed in the center of our Solar System, its radius would reach past the orbit of Jupiter. Nevertheless, stars like WOH G64 and Stephenson 2-18 are larger still.
