RW Cephei is an orange hypergiant star in the constellation Cepheus. One of the largest stars known, RW Cephei is estimated at 1,636 solar radii, which is larger than the orbit of Jupiter.
RW Cephei is also a semi-regular variable star of type SRd, meaning it is a slowly varying yellow giant or supergiant. Its surface is subject to pulsations in temperature and luminosity. Over the past 50 to 70 years it has varied from classes G8 to M0 with no discernible pattern.
