Tycho Brahe

Tycho Brahe (1546-1601) was the first observer whose measurements were sufficiently precise to enable the development of a model of realistic solar system: for him, the comments were intended to approach the reality of things easier that philosophical considerations. 

Tycho Brahe was a follower of coherent geo-heliocentric system with its observations. At this time, it was not possible to say that the Earth turn around the Sun or the other.
