Without reference to Galileo's tidal theory, there would be no difference between the Copernican and Tychonic systems. Galileo fails to discuss the possibility of non-circular orbits, although Johannes Kepler had sent him a copy of his 1609 book, Astronomia nova, in which he proposes elliptical orbits—correctly calculating that of Mars.

Nicolaus Copernicus's heliocentric model. Copernicus studied at Bologna University during 1496–1501, where he became the assistant of Domenico Maria Novara da Ferrara.He is known to have studied the Epitome in Almagestum Ptolemei by Peuerbach and Regiomontanus (printed in Venice in 1496) and to have performed observations of lunar motions on 9 March 1497.
Galileo Galilei, portrait by Francesco Porcia. Cardinal Bellarmine had written in 1615 that the Copernican system could not be defended without "a true physical demonstration that the sun does not circle the earth but the earth circles the sun". [85] Galileo considered his theory of the tides to provide such evidence. [86]
The Galileo affair (Italian: il processo a Galileo Galilei) began around 1610, [1] and culminated with the trial and condemnation of Galileo Galilei by the Roman Catholic Inquisition in 1633. Galileo was prosecuted for holding as true the doctrine of heliocentrism , the astronomical model in which the Earth and planets revolve around the Sun at ...
In 1610 Galileo Galilei observed with his telescope that Venus showed phases, despite remaining near the Sun in Earth's sky (first image). This proved that it orbits the Sun and not Earth, as predicted by Copernicus's heliocentric model, and disproved Ptolemy's geocentric model (second image).
Galileo establishes two main premises before addressing his conclusion. God has created Scripture and nature. They cannot contradict each other. Nature is independent of accommodation, but Scripture is produced to accommodate. [2] Galileo argued that the Copernican theory was not just a mathematical calculating tool, but a physical reality.
Copernicus' system used only uniform circular motions, correcting what was seen by many as the chief inelegance in Ptolemy's system. The Copernican model replaced Ptolemy's equant circles with more epicycles. 1,500 years of Ptolemy's model helped to create a more accurate estimate of the planets' motions for Copernicus. [31]
With the help of the telescope providing a closer look into the sky, Galileo Galilei proved the most part of the heliocentric model of the Solar System. Galileo observed the phases of Venus's appearance with the telescope and was able to confirm Kepler's first law of planetary motion and Copernicus's heliocentric model, of which Galileo was an ...
