Ptolemy Copernicus Tycho

Ptolemy Copernicus Tycho is an easy to use application that illustrates the relationships between the systems of planetary astronomy developed by Claudius Ptolemy, Nicholas Copernicus, and Tycho Brahe. 

Ptolemy Copernicus Tycho presents a simplified version of all three systems, showing the motions of the Sun/Earth and two planets (one inferior, one superior). 

Ptolemy Copernicus Tycho is initially set to model the planets Venus and Mars. In addition, the apparent motion of the sun and two planets across the sky is displayed in another window.
