Good news! The Solar System is doomed.

Better news! You probably don’t need to cancel anything this weekend.

A new study suggests that the long-term future of our Solar System may be considerably more chaotic than scientists previously thought. As the Sun reaches the end of its life, the way it loses mass could seriously mess with the gravitational balance keeping Jupiter, Saturn, Uranus and Neptune in their familiar orbits.

And when giant planets stop playing nicely with each other, things can get VERY weird.

So how unstable is the Solar System? What happens when the Sun becomes a white dwarf? Could planets actually get thrown completely out of the Solar System?

And most importantly…

How worried should we be about something that won’t become our problem for billions of years?

Let's talk about the eventual gravitational bar fight at the end of the Solar System.
