 RW Cephei

RW Cephei is an orange hypergiant star in the constellation Cepheus, at the edge of the Sharpless 132 HII region and close to the small open cluster Berkeley 94.One of the largest stars known, RW Cephei's radius is uncertain but somewhere between 800 and 1500 times that of the Sun (), thus larger than the outer limits of the asteroid belt, or possibly the orbit of Jupiter.
