Apr 3, 2005· Rejects Ptolemaic model because it fiddles with this assumption ("equants") --- not Aristotelian enough! In basic form (circular orbits around Sun), explains major phenomena more simply than Ptolemaic theory. Treats solar system as a system, not just one planet at a time.

Ptolemaic system

The ancient Greek geocentric model of the Solar System, as described by Ptolemy. It may be traced back through the work of, for example, Hipparchus, Apollonius, Callippus, and Eudoxus. and the orbiting body moved uniformly with respect to the equant.

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

How did Ptolemy''s model account for retrograde motion?

Feb 9, 2016· Ptolemy included epicycles in his orbits. Ptolomy''s model of the solar system was geocentric, where the sun, moon, planets, and stars all orbit the earth in perfectly circular orbits. The problem with perfectly circular orbit around the Earth is that they do not explain the occasional backward motion, or retrograde motion, of the planets. The Greeks insisted that the

Ptolemaic System Simulator

This simulator models the movement of planets around the sun in a simplified Ptolemaic model of the solar system, in which the Earth is motionless near the center. In this system, the sun circles the Earth once per year. Planets move on a large loop around the Earth - the deferent - and upon a smaller loop called the epicycle.
