According to Kepler's laws of planetary motion, planetary orbits are in the shape of an ellipse with the Sun at one of the foci.

Johannes Kepler proposed that planets move around the sun in an elliptical orbit through his three laws of planetary motion. This idea was further supported by Isaac Newton's law of universal gravitation, which provided a mathematical explanation for Kepler's laws.
Johannes Kepler is credited with forming the mathematics of elliptical orbits.
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."
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".

Johann Kepler
Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.

Sir Isaac Newton was the first to develop the three laws of motion.
No. Kepler discovered the laws using Tycho Brahe's data.
Johannes Kepler is the German astronomer who devised the three laws of planetary motion in the seventeenth century. These laws describe the motion of planets in elliptical orbits around the Sun.
Johannes Kepler is responsible for developing the three laws of planetary motion, which describe the motion of planets around the Sun. These laws are known as Kepler's Laws of Planetary Motion and were published between 1609 and 1619.
