After running nearly 3,000 simulations, scientists found that a minor change in Neptune's orbit caused by a passing star could disrupt our system's orbits.
Have you ever indulged the depths of your intrusive thoughts and wondered how the universe is going to smash and chew up our little planet over billions of years?
While they're not expecting a neighboring star to come cruising through the middle of our system, they looked at the potentially devastating effects of minor shifts in the orbits of the solar system's planets, triggered by a star getting a little too close to comfort — some billions of miles away.Brown and Rein ran nearly 3,000 simulations with varying degrees of perturbation caused by a possible stellar fly-by, examining the subsequent effects up to 4.8 billion years later.
The results are pretty shocking. The scientists found that just a 0.1 percent change in Neptune’s distance to the Sun could plunge the entire solar system into complete chaos — all because a star came within 23 billion miles of the Sun.
