Kepler spent over ten years analyzing the motion of Mars using Brahe's data before realizing that the circular models favored by Copernicus and Ptolemy could not explain the data. Key Scientific Contributions

The publication of Johannes Kepler’s Astronomia Nova in 1609 marked a definitive turning point in human history, shattering centuries of cosmological dogma. Moving humanity past the rigid perfection of circular orbits, this monumental work laid the foundation for modern astrophysics by introducing the first two laws of planetary motion.
The discovery of the elliptical path of Mars and the formulation of the first two laws.
Kepler found that a planet does not move at a uniform speed in its orbit. Instead, it moves faster when it is closer to the Sun and slower when it is farther away. 3. Celestial Physics (Physica Coelestis)
