All the known planets move in elliptical orbits around the Sun. This motion is governed by gravitational forces and described by Kepler’s laws of planetary motion, particularly the first law, which states that planets travel in elliptical paths with the Sun at one focus of the ellipse.
Additionally, while the orbits are generally elliptical, they can appear nearly circular for some planets due to their low eccentricity. This elliptical movement accounts for variations in speed and distance from the Sun throughout their orbits, contributing to the dynamic nature of our solar system.
