Celestial cycles refer to the regular patterns of movement and alignment of celestial bodies, such as the Earth, Moon, and Sun. These cycles include the lunar phases, which occur as the Moon orbits the Earth, and the solar cycle, which describes the Sun's activity over approximately 11 years. These predictable movements influence various natural phenomena, including tides and seasons. Understanding celestial cycles is essential for various fields, including astronomy, agriculture, and navigation. For example, farmers often plant crops based on the lunar calendar, while sailors use the positions of stars and planets to navigate. These cycles help us comprehend the rhythms of our universe.
