This week we evaluate the Copernicus heliocentric model of the solar system and compare it to Ptolemy's geocentric model. We then look at the model's reception by Erasmus Reinhold, Gemma Frisius, Michael Maestlin and Tycho Brahe. We conclude with Brahe's observations of the supernova of 1572 and the Great Comet of 1577.
