Important Contributions

Tycho was one of the few major "naked eye" astronomers, who put forward contributions to astronomy just before telescopes were developed and used widely by astronomers. Tycho was one of the few scientists who refuted the Copernican system and instead used elements of that combines with the Ptolemaic system to create his own Tychonic System. The tychonic system included the earth as the focal point for the solar system with the sun, moon, and other planets orbiting it, mainly for his religious beliefs.

"Yet in this my stars were not Mercury as morning star in the angle of the seventh house, in quartile with Mars, but they were Copernicus, they were Tycho Brahe, without whose books of observations everything which has now been brought by me into the brightest daylight would lie buried in darkness." -Johannes Kepler
