Planetary orbits are the paths that planets follow as they move around a star, such as the Sun, due to the gravitational force acting between the planet and the star. These orbits are typically elliptical in shape, as described by Kepler's laws of planetary motion, and are governed by Newton's law of universal gravitation, which states that every mass attracts every other mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. Understanding planetary orbits is crucial for comprehending how celestial bodies interact in space and the dynamics of our solar system.
