It was Claudius Ptolemy, 98-160. His Ptolemaic system describing the planets' movements among the stars was generally accepted for about 1400 years. Until the computer age, the Ptolemaic model was also used in planetariums.

The Ptolemaic system or the geocentric systemÊargues that the orbital center of the universe is the Earth. The system states that the moon, the other planets, the sun, andÊthe stars circled the Earth.
The Ptolemaic system belived that the earth was the center of everything and all the planet and sun traveled around it and the copernican system belived that the sun was the center of everything and the planets and traveled around the sun.
In Copernican scheme, the sun is the center of the solar system, while in the Ptolemaic system, the earth is the center of the universe and all the bodies of the universe revolve around it :) -iloveu armstrong11-12 Munsci :)
