Héliocentrisme et configuration du système solaire au temps de la révolution astronomique

Abstract : The rejection of the geocentric model, that was a crucial legacy from ancient astronomy, became the major paradigm shift brought by Copernicus’ discovery. But from a strictly scientific point of view, and as decisive as was the Copernican revolution in the 16th century, the new representation of the Cosmos remained in various points dependent on the one that was reversed. The following generations actually worked to refine the heliocentric scheme of the De revolutionibus orbium coelestium by clearing off its bulky rags. What part of the ancient legacy contained in Copernic’s planetary system was to be preserved, amended or rejected? What consequences did this have on the spatial representation that his disciples were trying to conceive, by correcting the imperfect sketches he had left to them? How to make use of the empirical data collected in the observation of planets, and how to reunite them with a geometric configuration likely to explain celestial mechanics? These are the main questions that this contribution attempts to answer, focusing on the influence of three scientists who played a decisive role in this field of cosmology: Nicolas Copernicus, Tycho Brahe and Johannes Kepler.
