Quizplus · Accepted Answer

The three laws of planetary motion were discovered by Johannes Kepler. Sir Isaac Newton did later provide an explanation for the laws through his theory of gravity, but he did not discover them initially. Tycho Brahe was an astronomer who made many observations of celestial bodies, but did not contribute to the discovery of the laws of planetary motion. Nicolaus Copernicus was an astronomer who developed the heliocentric model of the solar system, but did not discover the laws of planetary motion either.
