What is Kornephoros

Kornephoros, beta Herculis, is a yellow G-class giant that has left youth behind and entered its mature phase. Its Greek name means 'club-bearer', referring to the weapon slung on the constellation's shoulder. At 139 light-years it shines discreetly beside the more famous stars of the northern summer, yet reminds us that every constellation needs muscle as well as myth.
