Location of our Solar System in the Milky Way galaxy. However, for most of human history a geocentric model was the standard explanation of the cosmos. In this model the Earth is the the centre of the Universe and all the planets and stars revolve around it. Although it has been long superseded, this model could actually still be used to

Geocentric and Heliocentric Models

The Ptolemaic model of the solar system held sway into the early modern age; from the late 16th century onward it was gradually replaced as the consensus description by the heliocentric model. Geocentrism as a separate religious belief, however, never completely died out. In the United States between 1870 and 1920, for example, various members of the Lutheran Church–Missouri Synod published articles disparaging Copernican astronomy and promoting geocentrism. Howev

Geocentrism vs. Heliocentrism: Ancient Disputes

Ptolemy''s mathematics was able to explain, albeit in a very complicated way, all the apparent retrograde motions of the planets.

Similarities and Differences Between Geocentric and Heliocentric

In order to retain such motion and still explain the erratic apparent paths of the bodies, Ptolemy shifted the centre of each body''s orbit
