Astrology is a group of systems, traditions, and beliefs which hold that the relative positions of celestial bodies and related details can provide information about personality, human affairs and other "earthly" matters. A practitioner of astrology is called an astrologer. Astrologers believe that the movements and positions of celestial bodies either directly influence life on Earth or correspond to events experienced on a human scale. Modern astrologers define astrology as a symbolic language, an art form, or a form of divination. Despite differences in definitions, a common assumption of astrologers is that celestial placements can aid in the interpretation of past and present events, and in the prediction of the future.
Astrology is generally considered a pseudoscience or superstition by the scientific community, which cites a lack of statistically significant astrological predictions, while psychology explains much of the continued faith in astrology as a matter of cognitive biases.
