Kepler’s Third Law: The movement of solar system planets


Kepler’s Third Law is the last of the revolutionary theorems by German astronomers Johannes Kepler and explains planetary orbits around the sun.

Before Kepler outlined his laws of planetary motion in the early 17th century, humankind’s knowledge of the solar system and beyond was in its infancy and largely remained a mystery. At the time of Kepler the notion was that the Earth was the center of the solar system, and perhaps of the universe itself.
