∙ 9y agoGalileo's discovery of four moons orbiting round Jupiter were the first objects to be found that clearly did not orbit round the Earth, so it opened the question up.
His discovery of Venus's gibbous phase as is it emerges from behind the Sun to become the "Evening Star" every 18-20 months (as we now know) was a direct indication that the Ptolemaic system that had stood for 1400 years was incorrect. In the Ptolemaic system Venus passes between the Earth and the Sun at both inferior and superior conjunction, and therefore it must appear as a crescent both times.
However he was wrong in his claim that this proved that the Copernican system, with the Sun at the centre, must be right. Tycho's alternative system had the planets Mercury and Venus orbiting the Sun and then the Sun and the other planets orbiting the Earth. This allowed the full range of Venus's phases as shown in Galileo's telescope, while still preserving the Earth's place at the centre.
All these three early systems were rejected in favour of Kepler's model of 1609, with the Sun at the centre, when it was shown by Newton in the late 1600s that planets moving under the force of gravity must obey Kepler's three laws of planetary motion.

Why was Galileo Galilei hated by some people?
Because he was one of the first people to think the galaxy was heliocentric, but most people in his era believed it was geocentric.
Who were the people that Galileo got into trouble with?
Galileo got into trouble with the Catholic Church, specifically with the Roman Inquisition. They accused him of promoting the heliocentric theory proposed by Copernicus, which challenged the geocentric view of the Church. Galileo's ideas were viewed as heretical and he was forced to recant his views under threat of imprisonment.
What did Galileo Galilei do that was so important?
Galileo Galilei improved the telescope for his observations. He proved to the world that the earth revolved around the sun. Many people at that time period thought the sun revolved around the earth. Copernicus was actually the first to present the view that the earth revolved around sun but he was laughed at. Galileo proved the theory of Copernicus was correct. Even though Galileo proved this, people took a few years to accept this fact
The difference between the geocentric and heliocentric models and who developed them?
Geocentric model -- In a geocentric system Earth is at the center of the revolving planets. It is made by a Greek astronomer named Ptolemy. Heliocentric model -- In a heliocentric system Earth and the other planets revolve around the sun. It is made by Galileo.
Why did Galileo get locked up?
Galileo got locked up because the people from the church didn't believe him. They were were scared about what Galileo told the people
How did Galileo's version of the compass have an impact on people?
Ten million of galileo of a people
How would a camera of helped Galileo?
It would have helped people to believe him and his observations

Where did galieo discover Saturn?
Galileo did not discover Saturn. Saturn was known to people who lived thousands of years before Galileo. Galileo was the first person to see Saturn through a telescope, and the first to observe its rings. He made many of his observations from Venice.
What is the geocentric model of the solar system and what were some observations that led to that model?
Geo is Greek for Earth, so geocentric means the Earth is at the centre of the Solar System and everything, including the Sun, revolve round the Earth. Observations that led to this - well people see the Sun rise in the east and set in the west. Same with the Moon and planets. So they assumed that the earth was in the middle.
Why Aristotle believe in geocentric?
Aristotle believed in a geocentric model of the universe because it aligned with his concept of natural motion, where he believed that the Earth was the center of the universe and that celestial bodies moved in uniform circular motion around it. This perspective was also supported by observations of apparent motion of celestial bodies in the sky.
Who used a telesocpe to make detailed observations of the stars and planets?
Lots of people did, and still do. Astronomers do that all the time.
Did Galileo disprove the Bible?
Galileo made a small telescope with which he made scientific observations which went against the prevailing consensus around the system of Ptolemy. At that time many people, including religious leaders such as Luther and Calvin believed incorrectly that the system of Ptolemy agreed with the Bible. In particular, the Roman Catholic church, which had civil, as well as ecclesiastical authority, condemned the scientific observations of Galileo as heresy, and forced him to retract them under threat of death. It also seems that it was the scientific opponents of Galileo, those who supported the system of Ptolemy and Aristotle, who stood to lose the most by being proven wrong. The Roman Catholic church of the day was thus in a sense 'used' by this group to get the findings of Galileo suppressed. So, to put it simply, Galileo certainly demonstrated the folly of trying to marry the Bible to scientific theories which can and do become outdated. He certainly did not disprove the Bible itself, as the Bible does not support the system of Ptolemy. Yes. Both Gallileo and Copernicus disproved the Bible's teachings that the Earth was the center of the Universe. "The geocentric model held sway into the early modern age; from the late 16th century onward it was gradually replaced by the heliocentric model of Copernicus, Galileo and Kepler. Today, geocentric cosmology survives as a literary element within alternate history science fiction."
