Laws Of Planetary Motion


The Laws of Planetary Motion are a set of three fundamental laws that describe the motion of planets around the sun. These laws were first introduced by Johannes Kepler in the early 17th century and later refined by Sir Isaac Newton. The first law states that planets move in elliptical orbits with the sun at one of the foci. The second law, also known as the law of equal areas, states that a line that connects a planet to the sun sweeps out equal areas in equal times. The third law, also known as the law of harmonies, states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit. These laws have been instrumental in our understanding of the motion of planets and have been used to predict the positions of planets in the sky.
