The constellation Scorpio represents a great scorpion who fought toe to toe with the great hunter Orion. Scorpio is one of the largest constellations in the night sky. The bright star Antares, is the scorpion's heart.
According to the Greek mythology, Orion was envied by his lover's brother Apollo for being the most handsome man alive. Apollo went to Mother Earth and asked her to create a giant scorpion, which then stung and killed Orion.
