Kepler figured out the laws that describe planetary orbits. This enabled much more accurate planetary positions (which Kepler published), and set the stage for Isaac Newton to explain that gravity was the force that held the planets in their orbits.
Up until Kepler, everyone was sure that planetary orbits must be some form of perfect circle. His discovery that they are actually elliptical was an important turning point in the history of science, away from the Aristotelian method of applying philosophical concepts to physical reality, and towards modern empirical science.

He described how orbits work. This is really important to understanding how the planets go around the sun, how moons go around the planets, how the sun orbits around our galaxy, ect.
