Tycho Brahe's detailed observations of planetary positions paved the way for Johannes Kepler to discover the laws of planetary motion, which were instrumental in the development of modern astronomy. Brahe himself did not propose a heliocentric model of the solar system, nor did he discover the moons of Jupiter or the elliptical nature of planetary orbits.
