Kepler's Three Laws

Kepler has three laws of planetary motion. These three laws were:
1.) "The orbit of a planet is an ellipse with the Sun at one of the two foci."
2.)"A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time."
3.)"The square of the orbital period of a planet is proportional to the cube of the semi major axis of its orbit."

Below is an image of Kepler's Laws:

An example of Kelper's Laws is listed below in an image, This is very similar to the example we did of Kepler's Third Law which is also below.



 In my MSED 252 class we created a table dealing with Kelper's 3rd Law. We created the table below in an excel sheet as an example of these laws.

Planet Orbital Period (year) Orbital Period Squared Distance in AU (Cubed Root of orbital Period Squared)
Mercury 0.24 0.06 0.39
Venus 0.62 0.38 0.73
Earth 1.00 1.00 1.00
Mars 1.88 3.53 1.52
Jupiter 11.86 140.66 5.20
Saturn 29.46 867.89 9.54
Uranus 84.01 7057.68 19.18
Neptune 164.80 27159.04 30.06
