Constellation Hercules
Introduction
The constellation Hercules, also known as the “strongman,” is one of the largest constellations visible in the northern hemisphere’s summer sky. It is named after Hercules, a mythological hero known for exceptional strength and Twelve Labors.
Features and Mythological Connection
Hercules is best observed during the summer months. Its prominent features include the Hercules Cluster (M13), which is a dense globular star cluster, and the Keystone, a well-known asterism formed by four bright stars. Mythologically, Hercules is associated with the Greek mythical hero renowned for his strength and bravery. The constellation represents the hero’s likeness and his triumphs.
Notable Objects
Hercules Cluster (Messier 13): This globular cluster is located about 22,000 light-years away from Earth. It is composed of millions of stars tightly bound in a spherical shape, making it a popular target for amateur astronomers.
The Keystone: It is an asterism formed by four main stars in the constellation Hercules. It represents the torso of the mythological hero. The Keystone serves as a helpful guide for locating other objects within the constellation.
Epsilon Herculis: It is a binary star system consisting of two stars orbiting each other. Epsilon Herculis is the easternmost star in the Keystone asterism.
How to Observe Hercules
Hercules is most visible during the summer months in the Northern Hemisphere. Look for the constellation in the eastern sky, between the constellations Lyra and Corona Borealis. It is easily recognizable by its trapezoid-shaped pattern formed by the stars that make the Keystone.
