Final answer:
Kepler's analysis showed that the Sun was at the center of the planetary orbits, the speed of a planet varied throughout its orbit, and planetary orbits are elliptical.
Step-by-step explanation:
Kepler's analysis showed that the Sun was still in fact at the exact center of the planetary orbits. Kepler found that the speed of a planet varied throughout its orbit. Kepler's laws of planetary motion did not agree with theories he had before he analyzed the data. Kepler discovered that planetary orbits are elliptical, not circular. Tycho Brahe made most of the observations used by Kepler.
