In his book Mysterium Cosmographicum, Johannes Kepler proposed two
closely related issues: first, that there is a pattern of organizing space that accounts for the ratio of planetary distances; secondly, that these distances, measured from the physical body of the sun, are related to the periods of each planet. In light of this, Kepler thought he could prove a priori the correct order of the heavens, including their number and distances, and consequently prove Copernicus’ hypothesis. this article aims to understand the importance that Kepler gave to the a priori proof, and its role within his astronomical research program.
