(Latin: "Crab") In astronomy, the constellation lying between Leo and Gemini; in astrology , the fourth sign of the zodiac , governing approximately the period June 22–July 22.
It is represented as a crab (or crayfish), a reference to the crab in Greek mythology that pinched Heracles while he was fighting the Lernaean hydra. Heracles crushed the crab, but his enemy Hera rewarded it by placing it in the sky as a constellation.
