Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit . There are many different ways to mathematically describe the same orbit, but certain schemes, each consisting of a set of six parameters, are commonly used in ...
In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris.
