What is the essential difference between astronomy and astrology?

Astrology is a system that uses the relative position and motion of celestial bodies (especially the position of planets in the solar system) to explain or predict people's fate and behavior. From a scientific point of view, astrology is pseudoscience. It tries to explain people's character and destiny by birthplace, birth time and celestial position. All cultures in the world have very different astrological systems and theories. Astrologers also have different views on the scope of application of astrology. Some astrologers believe that astrology can objectively predict events that can be verified in the future, while others believe that the interpretation of astrology is only directional, and it cannot make predictions. In all cultures in the world, people once or still believe that astronomical phenomena have an influence on people. In astrology, the specific influence of any astronomical phenomena is limited to a specific place and time on the earth, and the influence of other places and times is different. Because all people on the earth see the same astronomical phenomena, the objectivity of astrology is only superficial. This is also the main criticism of astrology by natural science. Today's astrological predictions are generally symbolic, and most of them cannot be verified by physical science, so today's astrologers think that their knowledge has nothing to do with physical and natural science. But astronomy is a natural science that studies the structure and development of celestial bodies and the universe, including the structure, nature and operation law of celestial bodies. Born between heaven and earth, human beings began to explore the mysteries of the universe from a very early age, so astronomy is the oldest science, which is closely related to human labor and survival from the beginning. It is six basic disciplines with mathematics, physics, chemistry, biology and earth science. The study of astronomy is of great practical significance to our lives, such as timing, making calendars, and determining directions. The development of astronomy has had a great influence on human's view of nature. Heliocentrism of Copernicus once liberated natural science from theology; Kant and Laplace's theory about the origin of the solar system opened the first gap in the metaphysical view of nature in the18th century. An important subject in astronomy is the origin and evolution of various celestial bodies. The main research method of astronomy is observation, and constantly creating and improving observation means has become a topic that astronomers make unremitting efforts to. Astronomy, like other disciplines, always draws on and permeates many neighboring sciences. Every development of astronomical observation means has brought useful things to applied science. Astronomy follows the development path of observation-theory-observation, and constantly extends people's horizons to new depths in the universe.
