Ptolemy calculated the Sun to be the 4th object from the Earth, in between Venus and Mars.
Ptolemy's model is different from the earlier Greek model because Ptolemy developed a compllex geocentric model of the universe and his model seemed to explain motions until the 1500s.The early Greek astronomers believed that Earth was the center of the universe.
Brahe believed in the heilocentric model. Which the sun is in the center of the solar system.
Ptolemy's model of the universe did not exclude any reference to heaven. Claudius Ptolemy was a Greco-Roman mathematician and writer.
The mechanical model (gears and the like) of Copernicus is much easier to make than Ptolemy's.

Roughly, the Tycho Brahe model of the solar system was something between the ptolemic geocentric model of the solar system and the copernican heliocentric model. The sun still revolved around the earth but all other planets revolved around the sun. Interestingly, it was Tycho's pupil Kepler, that refined the Copernican model to include elliptical orbits (until then, orbits were assumed to be perfect circles).
In the late 16th century Tycho Brahe invented the Tychonian or Tychonic system which was a model of the solar system.
