The Sun orbits around Earth – and not vice versa. Copernicus had it 'upside down' Tycho Brahe was (almost) right. Copernicus was (completely) wrong - all along. Tycho's proposed 'geo-heliocentric' model had the orbits of the Sun and Mars intersecting - much like the vast majority of our visible star systems. In other words, he had correctly (yet unwittingly) interpreted the binary nature of our solar system. Since no binary star system had yet been observed in his time, Tycho had no way of making sense of his own observations. He then made a most horrendous mistake – i.e. when he entrusted the young Kepler to solve the baffling yet crucial & all-important behavior of Mars. The rest of this tragic 'mishap' (which has set back humankind's cosmo-logical knowledge by 400+ years) is recounted in due detail in Mr. Shack's, “the TYCHOS model” . http://www.tychos.info/ https://www.tychos.space/ Please refrain from using insulting comments, but rather have a lively discussion!
