Kepler's laws were initially formulated based on the observed motions of the six planets known during his time—Mercury, Venus, Earth, Mars, Jupiter, and Saturn. However, these laws apply universally to all celestial bodies that follow elliptical orbits around a central body, including exoplanets and moons. Since their formulation, Kepler's laws have been successfully used to describe the motion of various celestial objects beyond those known in the 17th century. Thus, while they originated from the study of six planets, their applicability extends far beyond that limited scope.
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.

Johannes Kepler was responsible for the three laws of planetary motion, known as Kepler's Laws. These laws describe the motion and orbits of planets around the Sun.
Isaac Newton
Johannes Kepler did not discover any planets, but he developed the laws of planetary motion which described the movement of planets around the Sun in elliptical orbits. These laws were crucial in advancing our understanding of the motion of celestial bodies.
Known for his eponymous laws of planetary motion.
Kepler's laws apply to the motion of planets around the Sun. Specifically, they describe the elliptical orbits of planets, the equal area law (planets sweep out equal areas in equal times), and the relationship between a planet's orbital period and its distance from the Sun.

It is Kepler's first law which says the planet moves in an ellipse with the Sun occupying one focus and the other focus is vacant.
The rules summarizing planetary movements are called Kepler's Laws of Planetary Motion. These laws were formulated by the astronomer Johannes Kepler in the early 17th century and describe the orbits of planets around the Sun.
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".

Kepler's Third Law, also known as the Harmonic Law, states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
Isaac Newton
Isaac Newton extended Kepler's laws by formulating his law of universal gravitation, which provided a physical explanation for the elliptical orbits of planets. His work, particularly in "Mathematical Principles of Natural Philosophy" (1687), showed that the force of gravity governs the motion of celestial bodies. Newton's laws of motion, combined with his gravitational theory, allowed for a deeper understanding of the dynamics of the universe, linking the motions of planets to fundamental physical principles.
