Aristotle described both systems, but insisted on adding "unrolling" spheres between each set of spheres to cancel the motions of the outer set. Aristotle was concerned about the physical nature of the
Today, it is our main source of information about the work of Hipparchus and other Greek astronomers. Ptolemy''s most important contribution was a geometric representation of the
Aristarchus knew the Sun was much bigger than the Earth or the Moon, and he may have surmised that it should therefore have the central position in the solar system.

Astronomy - Ancient Greece, Stars, Planets: Astronomy is present from the beginning of Greek literature. In Homer''s Iliad and Odyssey, stars and constellations are
Geocentrism, the idea that the Earth was at the center of the Solar System (or even cosmos) and that the other heavenly bodies, including the Sun, Moon, and the planets revolved around it,
Aristotle taught that rotating spheres carried the Moon, Sun, planets, and stars around a stationary Earth. The Earth was unique because of its central position and its material composition. All generation and corruption
