Johannes Kepler: Johannes Kepler, German astronomer who discovered three major laws of planetary motion. His discoveries turned Nicolaus Copernicus’s Sun-centered system into a dynamic universe, with the Sun actively pushing the planets around in noncircular orbits.

Eighty years later, calculus was discovered by Newton which enabled Kepler's laws to be derived mathematically. Kepler was given observational data by Tycho Brahe. He was given the task of explaining the motion of Mars from the data. Kepler's first law is that orbit of every planet is an ellipse with the sun at one of its foci. The equation of ...

This discovery (which became Kepler’s second law of orbital motion) led to the realization of what became Kepler’s first law: that the planets move in an ellipse (a squashed circle) with the Sun at one focus point, offset from the center.
