Its story

13 Cephei is a blue B8Ib supergiant, irregularly variable, set in the northern crown of the mythic King. Its radius exceeds ninety times the Sun's and it shines more than five thousand times brighter; its light takes some 2,500 years to reach us. It belongs to the lineage of suns doomed to spectacular ends —blue giants that will perish as supernovae, sowing heavy elements into the dust that will one day form new stars and new worlds.
