Problem 1 - The two satellites of Tethys and Dione follow circular orbits around Jupiter.
Tethys takes about 2 days for one complete orbit while Dione takes about 3 days. If the
wo satellites started out closest together on July 1, 2008, how many days later will they
Once again be at 'opposition' with one another?
A) Find the Least Common Multiple between the orbit periods.
B) Draw two concentric circles and work the solution out graphically.
What is the relationship between your answer to A and B?
