Geocentric model 地心说
(重定向自Geocentric universe)
In astronomy, the geocentric model (also known as geocentrism, or the Ptolemaic system) is a superseded description of the universe, where the Earth is at the center of all the celestial bodies. This model served as the predominant cosmological system in many ancient civilizations such as ancient Greece including the noteworthy systems of Aristotle (see Aristotelian physics) and Ptolemy. As such, they believed that the Sun, Moon, stars, and naked eye planets circled Earth.
