Perseus (astronomy)


A bright constellation of the northern hemisphere, near Cassiopeia. It is represented as the mythological hero; the head of the decapitated Gorgon, Medusa, is marked by Algol (Beta Persei), the best known of the eclipsing binary stars. During the second half of July and the first half of August the Perseid meteor shower radiates from its northern part.

Perseus lies in the Milky Way and contains the Double Cluster, a twin cluster of stars called h and Chi Persei. They are just visible to the naked eye as two hazy patches of light close to one another.
