He helped, but the idea had been advanced some decades before by the Polish astronomer Mikolai Kupernik, aka Copernicus, and actually centuries before that by Aristarchus, a Greek philosopher.

∙ 11y agoThe ancient Greek Ptolemy came up with a model of the solar system with the Earth at the centre. It worked reasonably well in predicting where the planets would be in the sky. In the 16th century Copernicus suggested that a better model could be considered with the Sun at the centre, but actually it was just as complex as Ptolemy's system.
Galileo picked a quarrel with the Pope over this but in the end he was put in court and asked for proof, but he could not produce any.
The idea that the Sun is at the centre was generally accepted after Newton's laws of motion and his law of gravity were discovered, and they support the idea that the Sun is at the centre, and now everybody including the Catholic church agrees it IS at the centre.

Who developed the heliocentric theory in ancient times?
No, the idea goes back to the ancient Greeks; Aristarchus of Samos, a mathematician and astronomer, is the first person (that we know of!) to have suggested the idea that the Sun was at the center of the solar system. But Aristotle insisted that the Earth was the center of all things, and his ideas were accepted. Copernicus was the first person to demonstrate mathematically how it would work, and his concepts have been generally proven to be correct. So he generally gets the credit.

How is the geocentric view different from the heliocentric view?
In astronomy, the geocentric model or the Ptolemaic worldview of the universe is the superseded theory that the Earth is the center of the universe and other objects go around it. Belief in this system was common in ancient Greece. It was embraced by both Aristotle and Ptolemy, and most Ancient Greek philosophers assumed that the Sun, Moon, stars, and naked eye planets circle the Earth. Similar ideas were held in ancient China.Two common observations were believed to support the idea that the Earth is in the center of the Universe: The first observation is that the stars, sun, and planets appear to revolve around the Earth each day, with the stars circling around the pole and those stars nearer the equator rising and setting each day and circling back to their rising point.[2]; the second is the common sense perception that the Earth is solid and stable it is not moving-but is at rest. The geocentric model was usually combined with a spherical Earth by ancient Greek and medieval philosophers. It is not the same as the older flat Earth model implied in some mythology. The ancient Greeks believed that the motions of the planets were circular and not elliptical, a view that was not challenged in western culture before the 17th century. 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 and science fiction. By Edem Uboh(Lead City University,Ibadan.)
What is The Sand-reckoner?
The Sand Reckoner was a mathematical treatise by Archimedes in which he tried to calculate the number of grains of sand that would fill the universe. His estimate used the heliocentric model of Aristarchus, but could not measure stellar parallax. It had many underestimations that yielded a universal diameter of only about 2 light-years, but coincidentally matched one value for the known observable universe (10^63 grains having 10^80 nucleons).
When was jupiters moons found?
Jupiter has at least 63 moons or satellites. The four biggest and brightest are Io, Europa, Ganymede and Callisto. These four were discovered in January 1610 by Galileo Galilei & they are collectively known as the Galileans, though they may have been seen slightly earlier by Simon Marius.The fifth moon, Amalthea was discovered by E.E. Barnard in 1892.The moon Metis was discovered in 1979 by Stephen P. Synnott.The moon Adrastea was discovered by David C. Jewitt and G.

2 models of the solar system?
Theres the Geocentric model, with earth at the centre and the planets and sun revolving around us. Then there is the Heliocentric model, with the sun at the centre and all of the planets including Earth revolving about it. The second model is the correct model, though for many years people assumed incorrectly that the Earth was at the centre of the universe.
Which diagram best represents a portion of the heliocentric model of the solar system?
