(N/A) Tycho Brahe $(1546-1601)$ was a Danish astronomer known for his incredibly accurate and comprehensive astronomical observations of the positions of stars and planets.
His primary contribution was the collection of a vast amount of precise observational data regarding the motion of planets,particularly Mars,over many years.
Although he did not formulate the laws of planetary motion himself,his meticulous data provided the essential empirical foundation for Johannes Kepler.
Kepler used Brahe's data to derive his three laws of planetary motion,which eventually paved the way for Isaac Newton to formulate the law of universal gravitation.
