Glossary term: Copernican Revolution

Description: The Copernican Revolution refers to the replacement of the geocentric (Earth-centered) model of visualizing the Solar System with a heliocentric (Sun-centered) model. The geocentric model was the consensus for close to two millennia, even though some believed that it was not accurate. This shift provided a realistic and accurate description of the motions of planets, stars, and other celestial objects in the sky. The geocentric model is still used for explaining concepts related to the celestial sphere. The Copernican Revolution is named after Nicolaus Copernicus, who described the heliocentric model in his seminal work De revolutionibus orbium coelestium. Although it is often claimed Immanuel Kant was the first to use the term Copernican Revolution, the accuracy of this claim is debated.
