An unexpected rescue mission could come in the form of a star flying by the solar system.
There's a slim chance the star could pull the Earth to a more habitable zone, a study suggested.
The researchers ran 12,000 simulations to see what would happen if a star passed within 100 astronomical units (about 9.3 billion miles) from Earth.
In 92% of cases, the solar system would remain almost intact even as a star passed by the solar system.
In some simulations, Earth remained in the solar system but was pulled to a region beyond Pluto that's about 10% cooler than our current orbit.
