Tycho Brahe |

| A meticulous observer, Tycho Brahe spent years tracking and measuring the movement of the planets, the sun, and the moon. The data, obtained with instruments of his own design, was remarkably accurate. Brahe's data played a crucial role in the development of astronomy; Johannes Kepler, one of Brahe's assistants, used the data to help him develop his famous three laws of planetary motion. | ||||||
