### Historical Significance

Johannes Kepler was a German astronomer and mathematician who deepened our understanding of the universe by modernizing Copernicus' heliocentric model. His work resolved several key discrepancies between the Copernican model and scientific observation by placing the planets in elliptical, rather than circular, orbits and mathematically describing their variations in orbital velocity. The framework of this model, which was later proven by Isaac Newton, is now known as Kepler's Laws of Planetary Motion.
