开普勒第一定律，也称椭圆定律，指出每一个行星沿椭圆轨道围绕太阳。

接着开普勒证明了这个椭圆轨道也能很有效解释其他行星的运行轨迹。然后他提出了行星运动定律，牛顿定律就是以此为理论基础的。
Kepler went on to show that an elliptical orbit is sufficient to explain the movement of the other planets and to devise the laws of planetary motion that Newton built on.
开普勒号则是第一个设计用来寻找地球大小的行星的望远镜，这些行星的轨道处于“可居住区域”内，温度既高也不太低，水份可以以液态形式存在，适宜生物生存。
Kepler is the first telescope to be designed to find Earth-sized planets that orbit in the "habitable zone" where temperatures are neither too hot nor too cold for water to remain in its liquid state.
相比之下在开普勒-10轨道中发现的那颗行星其轨道周长只有20小时，而且密度很高以至于研究员估计行星内部是由铁组成的。
