ee Figure 3 for an illustration of choosing the appropriate locations to measure for determining e period (indicated by red circles for Ganymede). As an example we will measure the period I lo. From the figure we determine there are 23 days between selected times (shown with white uares). There are 13 orbits (periods) executed during this time so 23 days/13 orbits gives 1.77 ays per orbit, or a period of 1.77 days. Convert this to seconds, and put your answer here: period (P) = seconds
