He did not need to discover that as it was already known by the ancient Greeks.
He discovered that the earth was round not flat.
Galileo Galilee proved that the earth is round by earths shadow on the moon.
Galileo observed that Jupiter had four moons constantly orbiting it, which challenged the idea that all celestial bodies revolve around the Earth. This observation indicated that there were other centers of motion in the universe and contradicted the geocentric model. Galileo's discovery provided evidence for the heliocentric model, which proposed that the Sun was the center of the solar system and supported the work of Copernicus.
He discovered that they orbit around Jupiter, the first example of anything that did not orbit round the Earth, which lent support to the idea that the Sun might be at the centre of the solar system. After Galileo's lifetime, with further scientific discoveries, this was discovered to be true
