Orbits of planets are in ellipse, where the sun is at one of the foci of the ellipse. Equal areas of the ellipse are swept out by the planets in equal imes: this means that speed is not uniform, though the area swept out per unit is the same. Constructed an equaion which showed that moion is slower when further away from the sun. Closer to the sun meant that the moion was faster. Explained compass workings earth is a magnet. Inspired kepler"s theory of anima motrix : moive soul: in the sun. Summary of kepler"s contribuion to the copernican worldview.
