Here's why:
* Newton's Law of Universal Gravitation: Newton formulated the law of universal gravitation, which states that every particle of matter in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
* Mathematical Proof: He mathematically proved that this force of gravity is what keeps the moon in orbit around the Earth and the planets in orbit around the sun.
* Kepler's Laws of Planetary Motion: Newton's work built upon the observations of Johannes Kepler, who had previously described the elliptical orbits of planets around the sun.
Therefore, while other scientists contributed to the understanding of gravity and planetary motion, it was Newton who provided the definitive mathematical framework and proof for the role of gravity in maintaining orbits.
