Copernicus put forward a model of the solar system with the Sun at the centre, which was repeated by Galileo. It remained a theory until after further refined theories and observations by Isaac Newton and others showed that the Sun is much more massive than the planets and must therefore stay at the centre.
He did not need to discover that as it was already known by the ancient Greeks.
Galileo did not discover that the Earth is a sphere; this fact was already known by ancient Greek astronomers. However, Galileo's observations through his telescope, including the phases of Venus and the moons of Jupiter, provided further evidence to support the heliocentric model of the solar system proposed by Copernicus, which implied that Earth was also a sphere.
Galileo discovered, in his observations of the different phases of Venus, that Venus and the Earth were revolving around the Sun. This was contrary to the misconception at the time that everything revolved around the Earth.
Galileo did not have his own theory, he was a strong supporter of the Copernican theory, which was a model that contained circles and epicycles, just like Ptolemy's ancient model, but with the Sun at the centre and the Earth in an orbit between the orbits of Venus and Mars. Galileo promoted the theory not only as a scientific theory, which the Vatican supported, but he maintained it was the absolute truth, which got him into trouble. At the same time as Galileo, Kepler brought out the improved model with elliptical orbits, which was generally accepted as the best model many years later.
Galileo used his telescope to look into space where he noticed that Nicalous Copernicus was correct in saying that the Earth revolves around the sun. Which Galileo was arrested for believing.
hi discoverd that earth was not a sqaur it was raound
The first man to discover that the earth moves around the sun was an Italian scientist named Galileo Galilei.
Galileo, happend in the late 1600s
It was the Italian Galileo who poved that the earth rotates round the sun.
He did not need to discover that as it was already known by the ancient Greeks.
Galileo. It's more complicated than that. Several people were involved. The main ones were Copernicus, Kepler, Galileo, and Newton.
