A new study by researchers from the Planetary Science Institute and the University of Bordeaux unveils that Earth faces a potential apocalypse scenario if flung out of orbit by a passing star. This grisly demise would plunge our planet into extreme cold without the Sun's heat. The probability of this happening is low—approximately 0.2% over the next five billion years. The study highlights that the stability of our solar system is less certain than previously thought, with Pluto identified as facing the highest risk among the planets.
"The long-term dynamical future of the Sun's planets has been simulated and statistically analyzed in great detail. But prior work neglects the influence of field star passages."
"We find a 0.3% chance that Mars will be lost through collision or ejection and a 0.2% probability that Earth will be involved in a planetary collision or ejected."
