A. Astrology is the study of how the sun, the moon, planets, and stars are supposedly related to life and events on the earth. It is based on the belief that the heavenly bodies form patterns that can reveal a person’s character or future. Many people throughout the world believe in astrology. These people base important decisions on the advice of an astrologer (a person who tells fortunes by studying the stars). Other people declare there is no scientific basis for astrology, and they consider it a form of entertainment.
B. Astrology differs from astronomy. Astrology developed from a set of principles that originated more than 2,000 years ago. At that time, astronomy was also based on those same principles. But during the 1500’s and 1600’s, several astronomers, including Nicolaus Copernicus of Poland and Tycho Brahe of Denmark, made discoveries about the heavenly bodies that conflicted with the principles of astrology.
