Celestial movements refer to the patterns and motions of celestial bodies, such as planets, stars, and moons, in the universe. These movements are governed by the laws of physics, particularly gravity, which causes objects to orbit around one another. For example, the Earth orbits the Sun, while the Moon orbits the Earth. The study of celestial movements helps us understand phenomena like day and night, the changing seasons, and the phases of the Moon. Observing these movements has been crucial for navigation and timekeeping throughout history, influencing cultures and scientific advancements.
