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. ___________________________________________ If you liked this week’s video, you might also like: That’s no moon … it’s a space station!
