When Galileo observed that the planet Jupiter has moons which are in orbit around the planet, this made it more believable that planets orbit the sun, since it was already established that not everything orbits the Earth, as had previously been believed in the Ptolemaic system.
They both belived that the Sun was in the center of the solar system.
Nicolaus Copernicus was the first to propose a heliocentric model of the solar system in the 16th century, which placed the Sun at the center with planets orbiting around it. Galileo Galilei supported Copernicus's ideas and used his observations through a telescope to provide further evidence for this model in the early 17th century.
Ptolemy thought that the Earth was the center of solar system and most people believed this theory. But Copernicus thought that the Sun was the center of solar system and most people didn't believed this theory. Who was right? Copernicus was right because later Galileo prove that if the Earth was at the center then he couldn't see the phases of Venus. Sentences for heliocentric. Galileo proved that the Copernicus's theory which was heliocentric was right.
Copernicus and Galileo were two major figures whose ideas contradicted Ptolemy's geocentric model. Copernicus proposed a heliocentric model with the Sun at the center of the solar system, while Galileo used observations through a telescope to support this view and challenge Ptolemaic beliefs.

Galileo and Copernicus
No, Nicolaus Copernicus proposed it 21 years before Galileo was born.
I am not sure they used similes. Copernicus postulated a sun-centered solar system through what today we would call reason and thought experiments. Galileo's careful observations through his telescope confirmed Copernicus's hypothesis.
Galileo Galilei
Copernicus proposed it, Galileo fought for it. It is called the Heliocentric model.
They both belived that the Sun was in the center of the solar system.

Nicolas Copernicus did not use a telescope, the use of the telescope to study the solar system was not done until over 50 years later by Galileo.

Copernicus created the mathematical theory to prove that the Sun, not the Earth, was the centre of our solar system. Galilei provided the calculations and observations to prove Copernicus' theory.
