Module 3: Orbits and
Systems
There is a relationship of the distances of planets from our Sun, usually called "Bode's Rule". You can read the details at the Bode's Rule Site . We will test this to see how good it is as a model. As a group, test Bode's Rule using the moons of one of the gas giant planets of our solar system. - Choose one of the outer planets
- Determine the orbital distance of 6 - 8 of its moons
- Select one of the moons to determine the standard AU for that system
- Apply the mathematical pattern to determine if the planetary system you choose follows the pattern.
In your groups, discuss: - How well does Bode's Rule work for our Solar System? How well does it work for the spacing of moon and ring systems around planets? Quanitatively and qualitatively?
- Are there any exceptions or "anomalies"?
- How good is this as a model? Does it help us understand the underlying science of planetary spacing? Can it make accurate predictions?
- What factors effect the result of your investigation?
- Does it work for other stellar systems?
Individually, submit the results of your group's investigtaion and summarize your group discussion into a few statements or paragraphs and submit it to the Module 3 Homework folder.
