Johannes Kepler (1571–1630) came up with the first astronomical model that potrayed motion. Using Copernicus heliocentric theory, he solved problems of planetary motion and came up with 3 laws of planetary motion:
- 1. Planets move at different speeds
- 2. Planets move in eclipses, not circles
- 3. When far from the sun, they are slow but when near to the sun they get faster
Kepler took a huge step in destroying geocentric and promoting heliocentric theory. His theories paved way for Law of Universal Gravitation (Newton) and freed people from Ptolemaic system, allowing them to think in a new way. However, like his predecessors, he could not explain the phenomena.
His work was banned by the Catholic Church while church reattempted to re-impose order and reassert power. Kepler was a religious man who credited God for all his discoveries.
