Sagittarius is the ninth astrological sign, which is associated with the constellation Sagittarius. Under the tropical zodiac, the sun transits this sign between approximately November 23 and December 21. The symbol of the archer is based on the centaur Chiron, who mentored Achilles, a Greek hero of the Trojan War, in archery.
Sagittarius, half human and half horse, is the centaur of mythology, the learned healer whose higher intelligence forms a bridge between Earth and Heaven. Also known as the Archer, Sagittarius is represented by the symbol of a bow and arrow.
