 The hypergiant star is near the end of its life. It's expected to explode as a supernova sometime in the next million years or so, just like Betelgeuse. RWS Cephei is low in the northeast at nightfall. It's about halfway between Deneb, the star at the tail of the swan, and W-shaped Cassiopeia. Even at its best, though, you need binoculars or a telescope to see it.
