___________________________________________

To learn more, start your googling with these keywords:
Moon: a natural satellite of a satellite of a star.
Satellite: A celestial body orbiting a larger celestial body.
Orbit: The path followed by one object revolving around another object under the influence of gravity.
Barycenter: The center of mass that two or more bodies orbit around.
Binary System: A system in which two similarly sized object orbit the same barycenter.
Hydrostatic equilibrium: Roundness that occurs when gravity is balanced by a pressure gradient force.
