Astrology is a system of beliefs that associates the positions of celestial bodies, such as planets and stars, with human affairs and natural phenomena. Astrologers believe that the positions of these celestial bodies at the time of a person's birth can affect their personality, relationships, and destiny.

Astrology is based on the idea that there is a correspondence between the movements of celestial bodies and events on Earth. The astrological chart, or horoscope, is a map of the positions of the planets at the time of a person's birth. Astrologers use this chart to interpret the influence of the planets on a person's life and to make predictions about future events.

While astrology has been popular for centuries and continues to be widely practiced today, it is not considered a scientifically valid way of predicting human behavior or events. Many skeptics argue that there is no scientific evidence to support the claims made by astrologers, and that any perceived connections between celestial movements and human affairs are purely coincidental.
