We know very little about planetary formation and star systems because till recently we could only study one. We can't study other ones well enough. So we have only highly speculative models.there is no computer model that ever predicts a solar system forming with inner rocky and outer gas giant planets?
Indeed, and the modelling suggests the gas giant spiralled in over time, ejecting other planetary bodies as it did so. Yet these "hot Jupiters" are surprisingly common, suggesting an awful lot of planets - and their moons - ejected to wander through interstellar space.We know now there are stars with gas giants in orbits closer than Mercury, which was a surprise.
There certainly are at least wandering stars and could be wandering planets. Not many.there is exactly zero planets or large bodies of any kind - wandering anywhere in space.
None, zilch. You can't move in or out,
