Kepler's laws of planetary motion describe the orbits of planets around the Sun. There are three laws: 1. First Law (Law of Ellipses): The orbit of every planet is an ellipse with the Sun at one of the two foci. 2. Second Law (Law of Equal Areas): A line joining a planet and the Sun sweeps out equal areas during equal intervals of time. This implies that a planet moves faster when it is closer to the Sun and slower when it is farther away. 3. Third Law (Law of Harmonies): The square of the orbital period (T) of a planet is directly proportional to the cube of the semi-major axis (a) of its orbit. Mathematically, this is expressed as: T² ∝ a³ Or, more precisely, for orbits around the Sun: T² = (4π²)/(GM) × a³ Where: T is the orbital period. a is the semi-major axis of the elliptical orbit. π is the mathematical constant pi. G is the universal gravitational constant. M is the mass of the Sun. These laws were derived empirically by Johannes Kepler from Tycho Brahe's meticulous astronomical observations and were later explained by Isaac Newton's law of universal gravitation.
