Stars Fly Past Planet, Saving World from Isolation

Astronomers have long theorized that planetary systems can be affected by stars passing near solar systems. However, direct evidence of this has never been seen, until now.
Sitting 300 light years from Earth, the star HD 106906 is accompanied by a planet 11 times the size of Jupiter, orbiting the pair of binary stars 738 times further away than the distance between the Earth and the Sun. Computer simulations show that roughly 12 million years ago, another pair of stars passed the system, altering the orbit of this giant world, pulling it far from its stellar companions. Had the encounter not taken place, this world would have crashed into the stars around which it orbits.
