The problem arose because astronomers 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.This was very strange if the earth was the centre of the solar system and all planets went round it.
Copernicus had thought long and hard about these problems and tried to find an answer.He had collected observations of the stars and used all his mathematical knowledge to explain them.But only his new theory could do that.So between 1510 and 1514 he worked on it,gradually improving his theory until he felt it was comple

这样,问题就来了,因为天文学家以前发现过,天上有些行星停顿下来,往后移动,然后再成环状向前移动,而其他行星看上去有时亮些,有时又不怎么亮.如果地球是太阳系的中心,而所有行星环绕着地球转的话,那么这种现象就很奇怪了.

哥白尼对这些问题曾经苦苦思索过很久,试图找出问题的答案.他曾经收集过观察星球的数据,并且利用他的全部数学知识来解释这些数据.但是只有他的新理论才能作出解释.于是,他在1510至1514年期间从事这项研究,逐步修改他的理论,直到他感到完善时为止.
