Just thought I would start a similar topic as the 'VOYAGER chronology' ... of course with nice diagrams

I worked the Horizons system a bit more and get the following c/a times and distances. Most are pretty close to the timeline Liss provided, with the exception of Phoebe (arguably not a close approach in either scenario!). According to these numbers, the undiscovered near-miss moon would have been Epimetheus at a distance of 6676km ... or about 6 minutes 45 seconds, given their relative speed of 59,271km/h!
Disclaimer: Horizon states that the trajectory data are reconstructed to fit the observations and is thus probably not as accurate as trajectory data available for current missions. Nevertheless:
