Tycho Brahe
Tycho Brahe was a Danish astronomer who lived between 1546-1601. For over twenty years he made observations of stars, comets, and planets in the night sky. Tycho also built the first observatory but did not use telescopes because they hadn't been invented yet.
Tycho's records were used by Johan Kepler to describe the orbits of planets around the sun.
