Final answer:
Saturn orbits the Sun in a nearly circular path with the Sun at one focus, not the center. Its speed varies throughout its orbit, being quicker at perihelion and slower at aphelion due to Kepler's second law. Saturn's average distance from the Sun is about 9.5 AU and it takes around 30 years to complete one orbit.
Step-by-step explanation:
Saturn's Orbit and Movement
The orbit of Saturn is an elliptical path around the Sun, with the Sun situated at one focus of this ellipse, not at the exact center. As a consequence of the elliptical shape of its orbit, Saturn does not move at a constant speed; its velocity varies, being faster when it is closer to the Sun (at perihelion) and slower when it is farther from the Sun (at aphelion). This movement conforms to Kepler's second law, which states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. In accordance with this law, the speed of a planet's orbit changes throughout its trajectory to conserve angular momentum.
Saturn's nearly circular orbit has an average radius of about 9.5 astronomical units (AU) and takes approximately 30 years to complete one full orbit around the Sun. The orbit of Saturn, like other planetary orbits in our solar system, is nearly circular, making its average distance from the Sun relatively constant compared to planets with more eccentric orbits, like Mercury.
