Our knowledge of the Zodiac constellations comes from astronomy. Astronomy is the study of the origin, movement, and behavior of stars and all the other material in the Universe. Astronomy is a science; it is based on repeated observations of the stars, and accurately predicts their motions and behavior. Some people confuse astronomy with astrology. Astrology is not a science but is the belief that the positions of the stars and planets in the Zodiac constellations can be used to predict how people will behave. There is no evidence that astrological predictions are accurate.
