Copernicus

he went to the university of krakow

It offered more natural explanation for the apparent retrograde motion of planets in our sky.

It didn't, at first. Copernicus was no better at predicting the exact position of the planets relative to Earth than was Ptolemy. This was because Copernicus was still relying on circular, uniform motion. Only when Kepler threw out circles for Ellipses with varying speeds did the predictions work.

Still, this was too subtle and mathematical for many Geocentric believers. The nail in the coffin was Gaileo's telescope, which showed "flaws" in the moon's surface, other moons orbiting Jupiter (not Earth), and Venus having phases that could only be explained by a sun-centered orbit.

go on Google its a great help! well once you look it up can you paste it on here i need a lot of help for my study guide

ANSWER: solar system

He suggested the orbits were circles.

that the world was heliocentric not geocentric aka sun centered universe and earth centered universe

People didnt believeCcopernicus because he had no scientific evidence until after he was dead and Galileo came along later.

Because it was found to be contradicted by observations when analysed in light of the laws of nature as discovered in the late 1600s. The main point is that the Sun was found to be many times more massive than the planets. The force of gravity on each planet acts equally on the Sun and the planet, but because the Sun is so much more massive it tends to stay in the same place.

That Earth went around the sun.

one of his greatest achievements were he was the first European astronomer to change the medieval belief system =)

Nicolas Copernicus was influenced by his uncle, after his father died when Nicolas was only ten. His uncle educated him. Also, note people spell his name many different ways so pick which one i guess..

no people did not belive that Copernicus model was correct. he thought that the moon revolves (turns) around the earth and the people thought something else (don't know sorry)

They believed in a universe with the Earth at the centre because the scriptures said that. At the start the Earth was the universe, and the sky was only a part of it. They had no reason to disbelieve the geocentric theory until adequate proof came that the Sun is at the centre, after Kepler's work on planetary observations and Newton's theoretical discoveries.

They proposed the idea that the sun is the center of the universe. this started the scientific revolution.

Copernicus proved to mankind that the sun was the center of the universe, not the Earth. We know now that he was mostly correct. The sun is the center of the solar system.

Copernicus was the first to argue that the world we live on, the Earth, revolves around the sun, rather than being the center of the universe around which all other celestial objects, the sun, moon, stars, and planets, all revolve, as had previously been believed. Even aside from the fundamental importance of this observation to the development of the science of astronomy, the Copernican Revolution helped people to overcome naive egocentricism, and to evolve a more sophisiticated understanding of what human beings are, and how we relate to the universe in which we live.

Nicolaus Copernicus was a true Renaissance man. He also was a lawyer, tax collector, a doctor, military governor, judge, vicar-general of canon law and a Polish astronomer. Nicolaus Copernicus said that the earth was not stationary. He also said the earth turned on its axis once a day and he doubted the earth lay in the middle of the universe. He claimed that the sun was the center of the universe and all the planets revolved around the sun. He also published a book on the revolution of the heavenly bodies. His book De Revolutions was his most famous piece of work.

I am actually doing a report on Copernicus. He took back what he said but right as he was dying they found out that he was right and his last words were. " I knew the sun was the center, all along."

Nicolaus Copernicus was a Polish astronomer. His greatest contribution was to assert that the earth revolves around the sun. At the time that Copernicus lived, the general conception was that the sun revolved around earth.

Copernican challenges beliefs by claiming sun-centered universe

It said that the Earth was in the center and the Sun, Moon, and other planets revolved around it. But this theory was wrong.
