In astronomy, the zodiac (Greek: ζῳδιακός, zōdiakos)
is a ring of constellations.

Each symbol of the zodiac represents one of the constellations that lines the ecliptic, which is the apparent path of the Sun across the celestial sphere over the course of the year.

The term zodiac derives from Latin zōdiacus, which in its turn comes from the Greek ζῳδιακὸς κύκλος (zōdiakos kuklos), meaning "circle of animals", derived from ζώδιον (zōdion), the diminutive of ζῶον (zōon) "animal". The name is motivated by the fact that half of the signs of the classical Greek zodiac are represented as animals (besides two mythological hybrids).
