Ellerdale - Geocentric model

topic information

general information about Geocentric model

In astronomy, the geocentric model (also known as "geocentrism, "geocentricism," or the Ptolemaic view of the universe), is the theory, now superseded, that the Earth is the center of the universe and other objects go around it. Belief in this system was common in ancient Greece. It was embraced by both Aristotle (see Aristotelian physics) and Ptolemy, and most, but not all, Ancient Greek philosophers assumed that the Sun, Moon, stars, and naked eye planets circle the Earth. Similar ideas were held in ancient China.
