Earth will become too hot to handle in a billion years. There's a (very) remote chance a passing star could save us by knocking our planet back into the habitable zone.
Still, it’s best not to put your money on a stellar savior. All these possibilities together amount to just a 1-in-35,000 chance that life on Earth will survive after the star whirs by, the researchers found. As Raymond noted in his blog PlanetPlanet, that’s roughly the odds of “randomly pulling the ace of spades from two separate decks of cards while also rolling a combined 10 with two dice. Not the best odds.”
Says so in the article:
Isn’t that more saying the chances of survival if a star manages to fly by us?
