It is the third law
The formula for newton third law is F=mg
Fa = -fb
Technically it doesn't precisely fit any of them, but to a first approximation it fits not only each of the planets, but every other orbiting body everywhere.
This is known as Keplers 2nd Law of Planetary Motion. It states that line drawn between a planet and the sun sweeps out equal areas during equal time intervals.
Kepler's second law the law of equal areas.
The third law states that for every action (force) in nature there is an equal and opposite reaction. YOUR WELCOME PPLZ!!!!!!! xD for every action there is a reaction
Newton derived Keplars findings from Newton's Theory of Gravity. Thus, newton 'explained' the basis for Keplars findings and extended them.
Kepler's first law says Neptune has an elliptical orbit with the Sun at one focus. The same goes for the other planets.
There is a relationship between the planets distance from the sun and the time taken for one orbit (planets year), described in Keplers third law. The square root of the time taken to orbit the sun is proportional to the cube of the average distance between the sun.
... when it is closest to the Sun. (Kepler's Second Law)... when it is closest to the Sun. (Kepler's Second Law)... when it is closest to the Sun. (Kepler's Second Law)... when it is closest to the Sun. (Kepler's Second Law)
Kepler's Laws of Planetary Motion:1] Each planet moves in an elliptical orbit with the sun at one focus2] The line form the sun to any planet sweeps out equal areas of space in equal time intervals3] The squares of the times of revolution (days, months or years) of the planets are proportional to the cubes of their average distances from the sun.
