Who said the moon sun and planets moved in circular orbits around the earth?

The idea that the moon, sun, and planets moved in circular orbits around the Earth is primarily associated with the ancient Greek philosopher Claudius Ptolemy. In the 2nd century AD, Ptolemy formulated the geocentric model of the universe, which placed the Earth at the center and proposed that celestial bodies moved in circular orbits, a concept that dominated Western astronomy for over a millennium until the heliocentric model was introduced by Copernicus.
