Kepler's three laws are important because they are used to predict the positions of planets years into the future. That is a help to navigators, astronomers and people planning space voyages.
Kepler's First Law of Planetary Motion, which states that planets orbit the sun in elliptical paths rather than perfect circles, challenged the classical astronomy belief that planetary orbits were circular and uniform. This shift underscored the complexities of celestial mechanics and the sun's central role in the solar system. Kepler's Second Law further refuted classical views by demonstrating that a planet moves faster when closer to the sun and slower when farther away, highlighting the variable speed of planetary motion and contradicting the notion of uniform circular motion.
It was Kepler. It's Kepler's 3rd Law of Planetary motion.
17th century astronomer Johannes Kepler discovered the elliptical shape of the planets' orbits around the Sun, which he described in his first law of planetary motion. Newton later explained this in his law of universal gravitation.
Kepler's laws of planetary motion refined the Copernican system by introducing the concept of elliptical orbits, replacing Copernicus's assumption of circular orbits. This shift allowed for a more accurate explanation of planetary movements and their varying speeds. Additionally, Kepler's laws provided a mathematical framework that supported the heliocentric model, enhancing its credibility and paving the way for Newton's law of universal gravitation. Overall, Kepler's work marked a significant advancement in our understanding of celestial mechanics.
Actually, Kepler's third law of planetary motion 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. This means that the farther a planet is from the sun, the longer it takes to complete one orbit.

Kepler's Laws of Planetary Motion.
Johannes Kepler was the person who first showed that planetary orbits are ellipses. His work, published in 1609, is known as Kepler's first law of planetary motion.
This is Kepler's second law of planetary motion, also known as the law of equal areas. It states that a planet moves faster when it is closer to the Sun and slower when it is farther away, so that the area swept out by a line connecting the planet to the Sun is equal over equal time intervals.

Kepler's 1st law of planetary motion state that Each planet moves in an elliptical orbit with the sun at one focus.
Laws of Planetary Motion by Johannes Kepler, published 1618.
Kepler's second law, also known as the law of equal areas, is a consequence of the conservation of angular momentum.
Kepler's First Law of Planetary Motion, which states that planets orbit the sun in elliptical paths rather than perfect circles, challenged the classical astronomy belief that planetary orbits were circular and uniform. This shift underscored the complexities of celestial mechanics and the sun's central role in the solar system. Kepler's Second Law further refuted classical views by demonstrating that a planet moves faster when closer to the sun and slower when farther away, highlighting the variable speed of planetary motion and contradicting the notion of uniform circular motion.
