The third law, sometimes called the harmonic law, allowed the relative distances of the planets from the Sun to be calculated from measurements of the planetary orbital periods. Kepler's laws gave a correct description of planetary motion. The physical nature of the motion was not explained ...

The law of periods was first discovered by German astronomer Johannes Kepler in the early 17th century. He observed that the orbital period of a planet was related to its distance from the sun, and through further calculations and observations, he developed the law of periods. Later, Isaac New...
Kepler's third law of planetary motion. The squares of the sidereal periods (P) of the planets are directly proportional to the cubes of their mean distances (d) from the Sun. © Encyclopædia Britannica, Inc./Patrick O'Neill Riley...
First, we show that Euler's 3-body orbit does not satisfy this "generalized Kepler's third law". Then we discuss the general implications of scaling symmetry, and of the virial theorem in particular, on periods of 3-body orbits in Newtonian gravity, to show that in the absence of a ...

The analysis of the observations relies on the fact that any tidal pattern (in time) is a superposition of variations associated with periodicities in the motions of the Moon and the Sun relative to Earth. The periods involved are the same everywhere, ranging from about 12 hours to a year ...
(which is on the right side of the ellipses, as shown). (Note: Since all the orbits shown below have the same size and semi-major axis, the orbital periods would be the same; since the areas, perimeters and speeds of the objects following such different orbits would be different, this...
Kepler's third law (in fact, all three)works not only for the planets in our solar system, but also for the moons of all planets, dwarf planets and asteroids, satellites going round the Earth, etc. What is the period law? The Law of Periods:The square of the period of any planet ...
3. The squares of the orbital periods of planets are directly proportional to the cubes of the semi-major axis of the orbits. Thus, not only does the length of the orbit increase with distance, the orbital speed decreases, so that the increase of the orbital period is more than proportiona...
