Planetary cycles refer to the regular patterns of movement and behavior exhibited by planets as they orbit around a star, such as the Sun. These cycles can include the rotation of planets on their axes, their revolution around the star, and the gravitational interactions with other celestial bodies. Understanding these cycles is crucial for predicting astronomical events and for the study of planetary atmospheres and climates. In addition to their orbits, planets also experience cycles related to their axial tilt and orbital eccentricity, which can influence seasons and climate over long periods. These cycles are part of a broader framework of astronomical phenomena that help scientists understand the dynamics of our solar system and beyond.
