Orbital revolution

From Wikipedia, the free encyclopedia

Orbital revolution is the cyclical path taken by one object around another object (or point, line, etc.)

In astronomy, the term revolution is most often used to describe the movement of large masses around the center of mass of a system, for example the movement of a moon around a planet, like a dog chasing its tail, or a planet around a star. These orbital revolutions were first described using elliptical orbits by Kepler. Newton later was able to provide a physical model for this motion, now understood to be due to the force of gravity. Our current understanding of gravitation, and therefore of orbital revolution, also owes a great deal to the Theory of relativity developed by Albert Einstein.
