Newton's theories, primarily articulated in his laws of motion and universal gravitation, describe how objects interact through forces, emphasizing the mathematical relationships between mass, distance, and gravity. In contrast, Kepler's theories focus on the motion of planets, specifically their elliptical orbits around the sun, outlined in his three laws of planetary motion. While Kepler's work provided the observational framework for planetary motion, Newton's laws offered the underlying physical principles that explain why those motions occur. Essentially, Kepler described the "how" of planetary motion, while Newton explained the "why."
Kepler's laws of planetary motion, which he formulated in the early 17th century, described the motion of planets around the sun but did not involve a formal understanding of gravity. Newton's law of universal gravitation, developed in the late 17th century, provided a theoretical explanation for Kepler's laws based on the force of gravity between masses. So Kepler did not believe in the same laws of gravity as Newton, but Newton's work built upon Kepler's observations.
Newton's derivation of Kepler's third law is an example of how theoretical physics can be used to explain and validate empirical observations. By applying his law of universal gravitation to Kepler's laws of planetary motion, Newton was able to mathematically derive Kepler's third law, providing a more fundamental understanding of the relationship between a planet's orbital period and its distance from the sun.
Galileo Gallilei (dont know how to spell his name) ,Johanes Kepler, and Newton Galileo saw the solar flares cycles, Keples created Kepler's three laws of planetary motion which proved Tycho Brahe wrong. Kepler showed that each planet rotates around the sun in an elliptical shape (which have two vertices, one being the center of mass between the two objects and the second being the center of gravity) Kepler was proved wrong because he did not have the theory of Universal gravity created by Newton 100 years later Hope this helps
Both Johannes Kepler and Isaac newton could fit that description.
Johannes Kepler said that IF the planetary orbits are elliptical,THEN that would explain the measurements that Tycho Brahespent his whole life collecting.Isaac Newton said that IF gravity works the way he thought it does,THEN the planetary orbits have to be elliptical.But neither Kepler nor Newton could ever say that the orbits are REALLY ellipses.Both of their statements are 'only theories', just like the theory of evolution.They have never been proven.

Kepler proposed a set of 'laws' to describe the motions of the planets,based completely on observational measurements.When Newton offered his law of universal gravitation, he was able to showmathematically that IF his formulas for gravity were correct, then the planetsMUST move exactly according to the observational measurements, and accordingto Kepler's Laws.That agreement was a great boost for these theories of both Kepler and Newton.
Kepler's Laws of Planetary Motion describe the motion of one object in orbit around another. Newton's Laws of Motion and the Law of Universal Gravitation describe how objects move in response to a force and how objects are attracted to each other.
Newton explained Kepler's laws of planetary motion using his laws of motion and the law of universal gravitation. Newton showed that Kepler's laws could be derived from his own laws, providing a cohesive and comprehensive explanation for the motion of planets in the solar system. By combining these theories, Newton was able to show that a single set of principles could explain both terrestrial and celestial motion.

Isaac Newton is the great mathematician and physicist who brought together the theories and discoveries of Copernicus, Kepler, and Galileo under his theory of motion, known as the laws of motion and universal gravitation. His work laid the foundation for classical mechanics and revolutionized our understanding of the physical world.
Johann Kepler.
Kepler's three "laws" of planetary motion constitute Kepler's explanation of the motions of the inner six planets of the solar system. He formulated them from years of sweating over the notebooks kept by another individual who spent his life watching the planets and keeping records of their motions. (Tycho Brahe). After Kepler's death, Isaac Newton developed his theory of gravity. Anybody who has enough geometry and calculus to give Gravity a good massage can show mathematically that IF gravity works the way Newton suggested it does, then the planets MUST move in the ways described by Kepler's Laws ... a nice confirmation of the work of both Newton and Kepler. These laws not only do a good job of describing how the planets move, but when we use Kepler's and Newton's formulas to figure out how to aim artificial satellites, Apollo capsules, and interplanetary probes to the outer solar system, those things always go where we want them to go ... more nice confirmation of the same theories. Oh yes. That's right. Both of them are "just theories".
Isaac Newton.
Kepler made discoveries regarding the planet's distance from the sun and how long it takes a planet to orbit the sun. In Newton's Version of Kepler's Third Law, Newton expands on these ideas by using his Theory of Gravity.
All orbits are ellipses, a sort of oval. Kepler's laws didn't give people enough information to actually calculate an orbit, but his work was fundamental to Isaac newton's work in developing theories of gravity and developing calculus.
