Nicoluas Copernicus was the first astronomer to propose the heliocentric theory. The heliocentric theory was first proposed by the Greek astronomer and mathematician Aristarc â¦ hus of Samos, in the 3rd century, BCE. The first predictive heliocentric mathematical model of the motion of the planets was developed by Nicholas Copernicus. 12 people found this useful.
  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.
