A list of different types of astrology and astrological traditions from around the world. In the most general sense, astrology is a belief system built on using observation of the heavens - genuine astronomical phenomenon - as a way to predict or understand events in the human world on Earth. In Western astrology, as well as a number of Eastern systems, the most heavy significance is placed on Zodiac types. In other words, the position of various stars, heavenly bodies, and constellations at the time of a person's birth, but there are numerous other variables that are measured and evaluated by astrologists and enthusiasts.
Throughout human history, astrology has been considered a genuine scholarly and academic tradition, and in many world cultures, it has a strong religious significance. The credibility of the "study" of the impact of stars on human events was dealt a serious blow during the Enlightenment era, when the science of astronomy began to bring a number of long-held astrological principles (such as heliocentrism) into doubt. Today, astrology is typically considered to be pure superstition or pseudoscience, though this does remain somewhat controversial in most world cultures.This list is a guide to all the worldwide astrology traditions that exist, a guide to the types of Zodiac signs and what they mean. Though many of these different Zodiac types are relatively old, with key principles and measurements dating back even thousands of years, some have been developed more recently, and even attempt to combine an ancient understanding of the zodiac along with a more modern interpretation of cosmology.
