Introduction to Planetary Orbits

The paths that planets take as they revolve around the Sun are known as orbits. In our solar system, all eight planets—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune—follow distinct, elliptical (oval-shaped) paths around the Sun. This motion is governed primarily by the law of universal gravitation, as famously described by Sir Isaac Newton, and the geometrical laws of planetary motion formulated by Johannes Kepler.
