The band is divided into 12 signs of the zodiac, each 30° long, that were named by the ancient Greeks after the constellations that used to occupy these positions; "zodiac" means "circle of animals," and only Libra is inanimate. Over the past 2,000 years, precession has moved the constellations eastward by over 30° so that they no longer coincide with the old signs. The 12 constellations of the zodiac are: Aries Taurus Gemini Cancer Leo Virgo Libra Scorpio Sagittarius Capricornus Aquarius Pisces Related category    • CELESTIAL MECHANICS Also on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History Transport Concepts & Designs (partner site) BACK TO TOP
