Asteroid Belt

If you deleted jupiter and left its moons, then those moons are suddenly flying through space without the gravitational force needed for their orbits. And so depending on their angles, like, they could plumb it into the sun or shoot out of the solar system. It's pretty fun to see, like the chaotic events that transpire when you mess with the solar system. You know, io could be a new planet, if you'd leat it j Jupiter.
