|zodiac (zō'dē-āk') Pronunciation Key
A band of the celestial sphere extending about eight degrees north and south of the ecliptic, representing the portion of the sky within which the paths of the Sun, the Moon, and the planets are found. In astrology, the zodiac is divided into 12 equal segments, each of which is named after a constellation through which the ecliptic passes in that region of the sky. The traditional beginning point of constellations is Aries, followed in calendrical order by Taurus, Gemini, Cancer, Leo, virgo, libra, Scorpius, Sagittarius, capricorn, Aquarius, and Pisces. See also equinox.
