What astronimer wrote 3 laws to describe planitary motion?

The astronomer who formulated the three laws of planetary motion is Johannes Kepler. These laws, published in the early 17th century, describe the elliptical orbits of planets around the Sun, the relationship between a planet's orbital period and its distance from the Sun, and the areas swept out by a planet in its orbit over time. Kepler's work laid the foundation for modern celestial mechanics and significantly advanced the understanding of planetary motion.
