Planetary orbits refer to the paths that planets follow as they orbit around a central star, such as the Sun. These orbits are typically elliptical in shape, meaning that they are slightly elongated rather than perfectly circular. The study of planetary orbits involves understanding the gravitational forces that influence the motion of planets, as well as factors such as orbital eccentricity, inclination, and precession. By studying planetary orbits, scientists can learn more about the structure and dynamics of our solar system, as well as the formation and evolution of planets. This research area is also important for predicting and understanding celestial events such as planetary transits and eclipses.
