He proposed the Geocentric model of the universe. In that model, the Earth was at the center and all planets orbited it. This was naturally inferred from the apparent motion of the Sun and stars as the Earth rotates.
He thought that everything moved round the earth. he surveyed over 1000stars and planets.
That the earth was the center of the universe.
Ptolemy's model of the universe did not exclude any reference to heaven. Claudius Ptolemy was a Greco-Roman mathematician and writer.
The mechanical model (gears and the like) of Copernicus is much easier to make than Ptolemy's.
The geocentric model.
Ptolemy calculated the Sun to be the 4th object from the Earth, in between Venus and Mars.
The idea first came from Aristotle, the Great philosopher of the fourth century B.C.
Ptolemy's model is different from the earlier Greek model because Ptolemy developed a compllex geocentric model of the universe and his model seemed to explain motions until the 1500s.The early Greek astronomers believed that Earth was the center of the universe.

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.
