Orbital laws refer to the principles that govern the motion of celestial bodies in space. The most well-known of these is Kepler's Laws of Planetary Motion, which describe how planets orbit around the Sun. The first law states that orbits are elliptical, with the Sun at one focus. The second law explains that a line connecting a planet to the Sun sweeps out equal areas in equal times, meaning planets move faster when closer to the Sun. Another important principle is Newton's Law of Universal Gravitation, which states that every mass attracts every other mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. This law helps explain why planets maintain their orbits and how gravitational forces influence their motion. Together, these laws provide a foundational understanding of how objects move in space.
