Well, I tried to remove Neptune in Universe Sandbox, it did nothing (as expected, tbf). I tried to remove all the planets except the Earth, and it spilled moons all over the solar system, but none even hit the Earth in a hundred years of simulation. Earth seemed to go slightly faster on the orbit (very slightly, though)
The sandbox looks pretty meditative, but also seems like it could do as a good education supplement, thanks for the hint
Check out Universe Sandbox on steam. Open the Sol system and delete a planet, change all the settings add black holes
