Kepler’s Laws

Tsokos 2-11

1. The motion of an object that is attracted and bound to a heavier mass is, according to the law of gravitation, an ellipse or circle.

2. Planets sweep out equal areas in equal times.

3. The period of a planet around the sun is proportional to the 3/2 power of the orbit radius.
