Iapetus goes crazy

Post #1by EarthMoon » 10.10.2022, 18:11

I found a very funny thing: Iapetus GOES CRAZY in a few centuries!

Just fly to Saturn and look at Iapetus' orbit.
It should be slightly elliptical and inclined.
Then set time scale to an extremely high value (like x10000000) or a very late time (e.g. 9999 Dec 31 23:59:59.9999).
Its orbit will be the craziest of all objects in our universe.

Or watch this:

Saturn: "Iapetus, why are you doing that?"
Iapetus: "VSOP87 forces me to do this!"

I believe this issue is already known, and is caused by issues with the trajectory.

But how to fix that (funny and annoying) issue?

You could edit solarsys.ssc to comment out Iapetus' CustomOrbit and uncomment its EllipticalOrbit definition, but keep in mind that will make Iapetus' orbit less accurate, at least close to the present.
