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: CODE 1979-08-29 06:06:10 Iapetus closest approach (1,032,535km)
1979-08-29 11:53:33 Phoebe closest approach (13,713,574km) 1979-08-31 12:32:33 Hyperion closest approach (666,153km) 1979-09-01 14:50:55 Epimetheus closest approach (6,676km) 1979-09-01 15:59:30 Dione closest approach (291,556km) 1979-09-01 16:26:28 Mimas closest approach (104,263km) 1979-09-01 16:29:34 Saturn Flyby (altitude: 20,591km) 1979-09-01 16:51:11 Janus closest approach (228,988km) 1979-09-01 18:25:34 Tethys closest approach (329,197km) 1979-09-01 18:30:14 Enceladus closest approach (222,027km) 1979-09-01 22:15:27 Rhea closest approach (345,303km) 1979-09-02 18:00:33 Titan closest approach (362,962km) -------------------- |
