Its story

53 Cassiopeiae is a hot blue B-type star more than 1,700 light-years away, set inside the stellar W of Cassiopeia. Despite that vast distance it reaches magnitude 5.59 thanks to a very high intrinsic luminosity, characteristic of massive stars of its class. Cassiopeia, which never sets at northern mid-latitudes, holds its zigzag silhouette between the pole and the Milky Way, where this blue giant sinks into the background river of stars.
