Document Summary

The earth is rotating around the sun not rotating in the middle. Earth rotating and jupiter rotating plotting points and seeing that the points went backwards as well. Planets follow a smaller circular orbit, predictable to retrograde. Mars has a larger retrograde motion because closest to earth while saturn as the smallest. Law of ellipses: every planet in solar system follows and ellipse around the sun which is the focus. Law of orbital harmony: for any planet, the square of the orbital period in year is proportional to the cube of the planets average distance from the sun. Law of equal areas: draw lines from planet to sun sweeps out equal areas in equal time. More mass at the equator than the axis. Winds due to earth moving in space. Asteroids hitting earth to move around space. If universe is stationary and finite university (there was stuff spread out), then it should collapse due to gravity.
