Ptolemy''s Model of the Solar System

The geocentric model of the solar system outlined above represents a perfected version of Ptolemy''s model, constructed with a knowledge of the true motions of the planets around the sun.

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
