A constellation is a group of stars that forms an imaginary outline or meaningful pattern on the celestial sphere, typically representing an animal, mythological person or creature, a god, or an inanimate object. Twelve ancient constellations are assigned to the zodiac (where the Sun, Moon, and planets all lie), which straddles the ecliptic. The origins of the zodiac, whose astrological divisions became prominent c. 400 BC in Babylonian or Chaldean astronomy, probably dates back to prehistory.
