Runaway Star Could Threaten the Entire Solar System — Scientists Sound the Alarm

A rogue star barreling through space could disrupt the solar system, scientists warn. Using Gaia data and computer simulations, researchers found even a 0.2% chance of Earth experiencing orbital instability. Mercury and Pluto face greater risks, with Pluto having a 4% chance of ejection. Though such events are billions of years away, the lesson is immediate: cosmic forces remind us to value Earth and invest in space science and planetary protection.
