The popular answer to this question would be Galileo. However, contrary to popular belief Galileo did not invent the telescope. He built his own telescope about a year after their initial creation and later made significant improvements.
Galieo was the first astronomer to view Jupiter's moons through a telescope and proved the heliocentric model.
The Polish astronomer who proved that the Earth revolves around the sun was Nicolaus Copernicus. His work laid the foundation for the heliocentric model of the solar system, challenging the geocentric view that had been dominant at the time.
Ancient Greek astronomer Aristarchus is the first person known to have proposed our Sun as the center of our solar system, but this view was rejected by all of his contemporaries and all subsequent astronomers for centuries afterwards. Nicholaus Copernicus took this idea and gave it mathematical and philosophical rigor.
As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
The earliest known proposal that the Sun was at the center of our solar system while the planets moved around it was by Aristarchus of Samos, a Greek mathematician and astronomer who lived in the 3rd century BC. (Others may have proposed it earlier, but no reference to them remains after 2400 years.) However, the views of Aristotle proved easier to accept. It wasn't until Copernicus developed the same theory (probably independently) based on more accurate and complete observational data that the heliocentric view of the solar system was widely accepted.
Galieo was the first astronomer to view Jupiter's moons through a telescope and proved the heliocentric model.
Galileo Galilei was the Italian astronomer who supported Copernicus's theories by using his own observations through a telescope to provide evidence for the heliocentric model of the solar system.
Galileo Galilei was an Italian astronomer, physicist, and mathematician known as the "father of observational astronomy" and the "father of modern physics." He made significant contributions to the fields of science by improving the telescope, supporting the heliocentric model of the solar system, and making important observations such as the phases of Venus and the moons of Jupiter. His work laid the foundations for the scientific revolution.
In the Dark Age of Science, it was believed that Earth was in the center of Solar System and all the planets including sun, revolve round the sun. This is called Geocentric Theory.Nicolas Copernicus, A Polish*Astronomer, proved that earth and other planets revolved round the sun. This is Heliocentric Theory.(Copernicus proposed the Heliocentric Theory in 1543, 64 years before the invention of telescope. I was all the work of his Mathematics.)_________________________________________________________________* Polish Astronomer is an Astronomer from Poland
Copernicus, with the use of the heliocentric theory and Galileo with his telescope proved the planets revolve around the Sun.
The Polish astronomer who proved that the Earth revolves around the sun was Nicolaus Copernicus. His work laid the foundation for the heliocentric model of the solar system, challenging the geocentric view that had been dominant at the time.
it wasn't
He made many experiments and observations in the field of physics in general.
Galileo had a theory, it was that the earth was NOT in the centre of the solar system like everyone thought, he made the first telescope and proved everyone wrong by looking into space and seeing that the sun was in the centre of the solar system, not the earth, doing this he also invented the telescope.

In 1610, Galileo used the telescope to discover four moons revolving around Jupiter.The motion of these moons proved that not everything in the sky revolves around Earth.Galileo's observation of Venus also supported the heliocentric system. Galileo knew that Venus is always seen near the sun. He discovered that Venus goes through a series of phases similar to those of Earth's moon.
