For a long time, people thought the Sun, stars and planets orbited Earth. In the early 1500s, Copernicus proposed that Earth and other planets orbited the sun. Few people accepted this idea at first. Why is this idea accepted now?

• It takes many years for scientific ideas to be proven correct.

• Many more observations have been made that support this idea.

• Controlled experiments were performed on the planets. The results of those experiments 

       support this idea.

  
  

• The ancient people were correct at the time. However, the positions of the sun and planets 

       kept changing. Now the planets orbit the sun.
