Johannes Kepler was a German mathematician, astronomer and astrologer, and key figure in the 17th century astronomical revolution. He is best known for his eponymous laws of planetary motion, codified by later astronomers based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy.
Before Kepler, planets' paths were computed by combinations of the circular motions of the celestial orbs. After Kepler, astronomers gradually shifted their attention from orbs to orbits. Kepler's laws also provided one of the foundations for Isaac Newton's theory of universal gravitation.
