The Ptolemaic model of the solar system held sway into the early modern age; from the late 16th century onward it was gradually replaced as the consensus description by the heliocentric model. Geocentrism as a separate religious belief, however, never completely died out.
  Copernicus's theory of 1543 places the Sun at the centre instead.  It explains some of the things that the Ptolemaic theory fails to  explain, like the full range of Venus's phases that Galielo  discovered. Galileo reasoned that this must prove that Copernicus's  theory is right.   However Galileo was wrong about this because Tycho Brahe's model  explains the phases of Venus correctly yet still has the Earth at  the centre.opernicus was dead so he didn't help him, but he helped prove his theory of heliocentrism. His telescope observations helped to prove the theory that everything revolves arou â¦ nd the sun, instead of the geocentric idea that everything revolved around the Earth.
