This ''revolution'' is a revolution of ideas. Copernicus started it by describing the Earth as one of many planets, but he treated celestial motion different from motion on Earth. Newton completed the revolution by showing that the same laws of motion work everywhere. In between them, Kepler found the first precise laws of planetary motion, and Galileo studied motion on Earth as well as celestial phenomena.
