A recent study suggests that an interstellar object, possibly as massive as eight times Jupiter, may have passed through the solar system billions of years ago, significantly altering the orbits of its outer planets—Jupiter, Saturn, Uranus, and Neptune. Using computer simulations, researchers found that in about 1% of the scenarios, such a close encounter could expl...
