The formulation of Kepler's Laws of Planetary Motion relied on the data and observations of Tycho Brahe.
The correct answer is Tycho Brahe. Kepler's Laws of Planetary Motion were formulated based on the data and observations collected by Tycho Brahe, a Danish astronomer. Kepler worked as Brahe's assistant and used his extensive observations of planetary positions and movements to derive his laws. Therefore, Tycho Brahe played a crucial role in Kepler's understanding of planetary motion.
