Common in ancient Greece, it was believed by both Aristotle and Ptolemy.Most Greeks assumed that the Sun, Moon, stars, and planets orbit Earth.Similar ideas were held in ancient China.he geocentric model was gradually replaced by the heliocentric model of Copernicus and Galileo due to the simplicity and predictive accuracy of that newer model. In this model, a set of fifty-five concentric crystalline spheres were considered to hold the Sun, the planets, and the stars.
