was to seek physical causes for planetary motion, a radical break from tradition. For this, he relied on the most precise astronomical observations of his time, bequeathed to him by his mentor, Tycho Brahe . On his deathbed in 1601, Brahe implored Kepler to continue his work and, in a sense, to see that he did not "die in vain". Kepler honored this request but transcended it entirely, using Brahe’s data to forge a new celestial physics that rejected all prior systems—Ptolemaic, Copernican, and even Tycho's own geo-heliocentric model. Mars was the key to his discovery because its orbit has a more noticeable eccentricity than most other planets (except Mercury), making deviations from a perfect circle easier to detect.
