Intruder star approaches a solar system
This suggests what could happen if a wandering star came near our solar system.
Of the original four planets, one is captured by the intruder star, one is ejected into empty space, and the other two have their orbits wildly disrupted.
There may be many lone planets in interstellar space, created by events like this.
