â¢ In the geocentric model, the earth is considered as the center of the universe, and all celestial bodies move around the earth (planets, moon, sun and the stars). â¢ In the heliocentric model, the sun is considered as the center of the universe, and the celestial bodies move around the sun.
The heliocentric theory, on the other hand, states that the earth revolves around the Sun. The first advocate of a heliocentric model was Aristarchus of Samos in ancient Greece. Centuries later, Nicholaus Copernicus developed a geometric model of the heliocentric theory during the Renaissance.
