Orbital elements are a set of parameters that define the shape, orientation, and position of an orbiting body, such as a planet or satellite. These elements include the semi-major axis, eccentricity, inclination, longitude of the ascending node, argument of periapsis, and true anomaly. Together, they provide a complete description of the orbit's characteristics. These parameters are crucial for predicting the future positions of celestial objects and understanding their motion. For example, the Earth and Moon have specific orbital elements that determine their paths around each other, influencing phenomena like eclipses and tides.
