Sagittarius, the "Archer", is a constellation, one of the twelve Signs of the Zodiac. The shape of the constellation was thought to resemble a Warrior-Centaur ready to loose an arrow. Its name is derived from the Latin word sagitta, meaning "arrow". An image of an arrow piercing a body and passing from front (anterior) to back (posterior) on a parabolic trajectory would be one way to demonstrate the derivation of the term. The Archer, Sagittarius, is the ninth astrological sign, and comes between Scorpio the Scorpion and Capricorn the Sea-goat. As a sun sign, it represents the dates of November 23 through December 22.
