How did galileo’s work as an astronomer contribute to the acceptance of copernicus’s heliocentric system

Galileo used his telescope to prove that Copernicus's theory was right, that indeed the sun was in the center of the solar system rather than the earth from Ptolemy's geocentric theory.
Galileo found Jupiter's moons and Saturn's rings and supported the argument that the earth, therefore, was not at the center or else everything would be center on earth.
