I need help finding answers to the following questions if any of you know the answer:
1-Why was mars the best planet that Kepler could have studied to derive his law?
2- How does the sun do work on earth?
3- If a new planet is discovered that is 4 times farther from sun than earth how long would it take this new planet to orbit the sun?
4- What are two differences between Ptolemaic and Copernican systems of planets?
5- What behavior of the moon allows us to only see the same side?
 
I'll give you some clues, but I won't do your assignment for you.

1. Compare the eccentricities of the 5 known planets at the time.

3. Look at Kepler's Third Law

4. Look up the center object of each model. Also look up epicycles.

5. Look up "tidal lock."
