Galileo did not directly provide evidence for the heliocentric principle but he did discover important evidence that raised doubts about the Ptolemaic system with the Earth at the centre. First, he discovered the moons of Jupiter, and these were the first objects discovered that definitely orbited round something that was not the Earth. That was one thing. Secondly, he discovered that Venus has a gibbous phase when seen from Earth in certain positions in its orbit. This is not explained by the Ptolemaic system because Venus cannot go round behind the Sun in the Ptolemaic system. Again this did not prove the heliocentric principle because Tycho Brahe came up with an intermediate system that had Mercury and Venus orbiting round the Sun, and then the Sun and the other planets orbit round the Earth. So this was still a geocentric system that explained all Venus's phases. Therefore Galileo did not have enough evidence to prove the heliocentric principle, and after his trial he recanted. But 60-70 years later enough new evidence had been gathered to convince most people that the Sun is at the centre, as we believe now.

He proved the heliocentric model to be right about the Sun being in the center of the solar system and not the Earth.
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.
200 billion years ago
No, Nicolaus Copernicus proposed it 21 years before Galileo was born.
The Jovian moons. Galileo had little evidence for the heliocentric theory, which was later (in the 18th century) generally accepted as correct after the laws of motion and the law of gravity showed that the Sun is by far the most massive object in the solar system and therefore must be at the centre. Galileo did not have the other major piece of evidence supporting the heliocentric theory, which is the parallax shown by relatively close stars as the Earth moves round its orbit. Parallax is extremely small and was impossible to observe in Galileo's time, and this was used to support the idea that the Earth is at the centre. Bessel made the first measurements of parallax in the 19th century.

the heliocentric system and the geocentric system
Galileo
Copernicus proposed it, Galileo fought for it. It is called the Heliocentric model.
Galileo's work came into conflict with the church because he advocated a heliocentric model of out solar system. This conflicted with what it says in The Bible.
The heliocentric idea, with the Sun at the centre, was part of a prediction model using circles and epicycles devised by Copernicus, called the heliocentric model. The heliocentric idea was adopted by Kepler in his work that led to the discovery of Kepler's laws of planetary motion. It was also used by Galileo in a famous dispute with the Catholic church which was not about to change its ideas without adequate evidence. The evidence came after Galileo's time when Newton made the necessary theoretical discoveries to understand the way the Sun's gravity produces planets' orbits. Since then everyone believes that the Sun is at the centre.
