The laws of physics govern the behavior of celestial bodies from "summary" of The Mysteries of the Universe by Will Gater
In the vast expanse of the universe, celestial bodies such as planets, stars, and galaxies are governed by the fundamental laws of physics. These laws, which have been meticulously studied and tested by scientists for centuries, establish the rules that dictate the behavior of these cosmic entities. One of the most important laws that apply to celestial bodies is the law of gravity, first described by Sir Isaac Newton. This law states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This fundamental force of nature is responsible for keeping planets in orbit around stars, moons in orbit around planets, and stars in orbit around the center...
