The earth was not the centre of the solar system. Only if you put the sun there did the movements of the other planets in the sky make sense.
3. What had the astronomers noticed in the sky? (Para 2) 4. When did Copernicus complete his theory? (Para 3)
5. How did he explain changes in the movement of the planets and in the brightness of the stars? When did he publish his idea? (Para 4)
He placed a fixed sun at the centre of the solar system with the planets going round it and only the moon still going round the earth. He also suggested that the earth was spinning as it went round it.
3. What had the astronomers noticed in the sky? (Para 2)
They had noticed that some planets in the sky seemed to stop, move backward and then go forward in a loop. Others appeared brighter at times and less bright at others.
4. When did Copernicus complete his theory? (Para 3)
Between 1510 and 1514 he worked on it, gradually improving his theory until he felt it was complete.
Because his theory is now the base on which all our ideas of the universe are built. His theory replaced the Christian idea of gravity. He showed this was obviously wrong.
