I wonder what the predictions are like. When it finally gets to Jupiter, eight years from now, do we know now where the moons will be ? To what accuracy ?

I believe orbits are chaotic over a timespan of many millions of years (due to weak interactions with multiple other bodies), but accurately predictable over a human lifespan.

I just wonder whether they can say that, on date&time X1 (98% sure to be accurate within E1 hours) we know satellite Z will be X2 thousands of km away (98% sure to be accurate within E2 km).
