Johannes Kepler (1571–1630) - Johannes Kepler

Johannes Kepler (1571–1630): Johannes Kepler was a German astronomer, mathematician, and astrologer whose innovative work transformed our understanding of the cosmos. Kepler formulated three major laws of planetary motion which corrected and refined the previous heliocentric model proposed by Nicolaus Copernicus. His laws accurately described the elliptical orbits of planets around the sun and the relationship between a planet’s orbital speed and its distance from the sun. Giving us the precise correlation between the orbital periods of any two planets. These laws provided a powerful model for planetary motion and formed a vital link in the chain of scientific understanding that led to the formulation of Newton’s law of universal gravitation.
