Sagittarius (♐) (Greek: τοξότης Toxotes, Latin: Sagittarius) is the ninth astrological sign, which is associated with the constellation Sagittarius and spans 240–270th degrees of the zodiac. 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 in archery [Achilles was a Greek hero of the Trojan War and the greatest warrior of Homer's Iliad].
