I have created a planetary system consisting of a Super Jupiter (10 Jupiter Masses) and up to 8 Earth Sized/mass Moons (on average) and now I wonder if it would be stable.
I already tried to create it in Universe Sandbox2, but US2's Game Speed drastically reduces if I would add so many bodies into one simulation, so I am not sure how long it would be stable. (I'm talking about a time span of several billion years.)
So I decided to bring this up here: The 3 innermost moons you can see have a mass of between 0.6 and 0.7 Earths. Their orbits have a distance of 290000-300000 KM to each other.
The next 3 are basically remains of a collision, so their mass is not impactfull to the systems integrity.
However, the next group of Moons consists of bodies being 0.9, 1.6 and 0.8 as massive as earth and having an orbital distance of aprox. 700'000 KM to each other.
And finally, the two last objects are two super-earth-sized moons with 11 and 16 Earth Masses. Both of these have their own subsattelites.
The Lunar System has a witdh of 850000KM to 1,0472e+9 km.(0.07 AU).
Edit: The Gas Giant has an orbit of 3.7 AU to its sunlike star.
