Johannes KeplerJohannes Kepler
1571-1630 German astronomer Known for his laws of
planetary motion
Law 1: Orbits Law 1: Orbits are Ellipticalare Elliptical
Law 2: Speed of PlanetsLaw 2: Speed of Planets
It takes a planet the same amount of time to go from A to B as it does from C to D = the closer they are to the sun the faster planets move.
The square of any planet’s orbital period is proportional to the cube of its mean distance from the sun
Law 3: PLaw 3: P22 = A = A33
