Galileo's observations of Jupiter and its moons provided compelling evidence against the geocentric model, which positioned Earth at the center of the universe. By observing the four largest moons of Jupiter, now known as the Galilean moons, he demonstrated that not all celestial bodies orbit the Earth; instead, these moons orbited Jupiter. This contradicted the geocentric view and supported the heliocentric model proposed by Copernicus, which posited that the planets, including Earth, orbit the Sun. Galileo's discoveries marked a significant shift in our understanding of the cosmos, highlighting the complexity of celestial mechanics.
Jupiter's moons orbited it and thus did not have a the earth as their axis of rotation.
Galileo's observation of Jupiter's moons orbiting another planet showed that not all celestial bodies revolved around Earth, contradicting the geocentric model that placed Earth at the center of the universe. This supported the heliocentric model proposed by Copernicus, which placed the Sun at the center with planets, including Earth, orbiting around it.
Galileo reasoned that the phases of Venus could not be explained, if the Earth is in the center of the system of the planets. So Ptolemy's geocentric system could not be correct. Edit: That's correct, but it doesn't answer the question, which is about Jupiter. The idea is that Jupiter having moons proved that there are other places that can be centres of motion, apart from Earth.
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
Galileo discovered the moons of Jupiter, which were the first objects discovered that orbited round something other than the Earth. Before then, it was assumed that everything in the universe rotated around the Earth. Galileo discovered objects revolving round Jupiter, but that on its own did not show that the geocentric Ptolemaic model was wrong.
I have no idea so u need to help me on this question

Galileo's found that these moons revolved around Jupiter, not Earth, thus demonstrating that it was possible for celestial objects to revolve around something other than Earth.
Galileo's observation of Jupiter's moons provided direct evidence that not all celestial bodies revolve around the Earth. By observing the moons orbiting Jupiter, he showed that there are objects in the universe that do not orbit the Earth, contradicting the geocentric model which placed Earth at the center of the universe with all celestial bodies orbiting around it.

The observation of the moons orbiting the planet Jupiter made by Galileo. This proved that not everything revolved round Earth/Rome.

The first recorded observation of Jupiter was by Babylonian astronomers in the 7th century BCE. Since Jupiter is the fourth brightest object in the night sky, it has always been observed by mankind.
