Kepler’s laws describe the motion of astronomical bodies and were discovered by Johannes Kepler. They paved the way for Isaac Newton’s theory of interaction of bodies. The laws state that planets follow elliptical paths, trace out equal areas in equal times, and the square of the period of the orbit is directly proportional to the […]
Kepler’s third law states that the square of a planet’s orbital period is proportional to the cube of its semimajor axis. This applies to all celestial bodies in orbit and explains why planets closer to the sun move faster than those farther away. The law can be expressed as (P1)2/(P2)2 = (R1)3/(R2)3 and is demonstrated […]
