Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the moon.
No. The above answer is incorrect.
Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the EARTH in epicycles. Not the moon. (The model that modeled the planets orbiting earth was the Geocentric model. Aristotle theorized this.)
Copernicus's model is known as the Heliocentric model. Ptolemy's theory of epicycles is when the planets revolved in large circles around Earth.
