2 Bodies Appulse
#2
Hi Steve,

That's a pretty unusual use of the appulse finder. I am not sure that anyone has tried finding appulses between the planet and a moon before. I doubt that I have. I'm happy to hear that it works for so many!

As for why Iapetus might be failing, have you tried making the search period longer? Iapetus has a 79 day orbital period. The appulse finder is very sensitive to the search time. If too short it is prone to fail. There is code internally that adjusts the parameters to keep this from happening, but it is set on a case by case basis and it may not be set up for planetary satellites. Try a search period of 160 days or more.

So now I am really curious: why are you interested in knowing when the moons are closest to the planet?
Clear skies,
