What Is An Orbital Revolution?

Orbital revolution is basically the recurring pathway, which is basically taken by one object and moved around another object.

In terms of astronomy it refers to a kind of a movement of big huge masses, which generally surrounds the centre of mass of a particular system.  An example of a movement could be a moon moving around the planet. Such a revolution was earlier known as elliptical orbits by Kepler. It was only later that Newton offered a physical model to this kind of motion. It was after this that the Theory of relativity  was developed by Albert Einstein.
