Sagittarius

Sagittarius is most commonly referred to as the ninth sign of the zodiac. A person born when the sun is in Sagittarius is called a Sagittarius as well. A Sagittarius would have to be born from November 22 to December 21. The Eleventh Doctor once said to Solomon, "I'm a Sagittarius. Probably." (TV: Dinosaurs on a Spaceship).

The word may also mean a constellation that represents a centaur carrying a bow and arrow. The center of the galaxy is situated inside this constellation.
