Kepler's Validation of the Third Law of Motion

Johannes Kepler confirmed the third law of planetary motion after initially rejecting it. Originally discovered on March 8, Kepler was led to doubt the law due to discrepancies in his early calculations. However, upon re-evaluating his data and considering the implications of his earlier work on the movements of planets, he recognized the robustness of his findings and publicly validated the law in May 1618. This pivotal moment reinforced the foundations of celestial mechanics.
