(3) Ptolemy (2nd cent) used epicycles to explain retrograde motion of planers. (4) Copernicus (16th cent) proposed a heliocentric model for the universe. (5) In the model of Copernicus, retrograde motion is easily explained. Ptolemy's geocentric model was based on the idea that Earth is the center of the universe, while Copernicus's heliocentric model was developed around the idea that the Sun is at the center. While these two models were based on opposing ideas, they shared a common belief in uniform circular motion and the use of epicycles.

Ptolemy invented the most elaborated geocentric system, allowing the planets not only to move on circles around the earth, but using epicycles. By adding further ideas, he was able to predict the motion of the planets quite well. Ptolemy's model was extremely popular from ancient times until the 1600s, as it had better agreement with observation than any alternative. In astronomy, the geocentric model (also known as geocentrism, or the Ptolemaic system), is the superseded theory that the Earth is the center of the universe, and that ID: G15JD2 (RM) 2021-4-23 · In astronomy, the geocentric model of the universe is the disproved theory that the Earth is at the center of the universe and the Sun and other objects go around it.
