Earth's motion around the Sun, not as simple as I thought

The video explores the complexities of Earth's motion around the Sun and its impact on the length of a year and seasonal changes. It discusses different methods of measuring the year and highlights influences such as the precession of the Earth's axis and the gravitational forces of the Sun and moon. It also explains how the elliptical shape of Earth's orbit affects the distance from the Sun and contributes to temperature variations throughout the year. Overall, the video emphasizes the numerous factors that contribute to the complexity of Earth's motion around the Sun.
