Star may come within 0.2 light yrs of Earth in 1 million yrs
According to a Polish study, a star named Gliese 710 which is currently 64 light years away from Earth, could come as close as 0.2 light years of Earth in just over a million years. Scientists have suggested that the sun-like star could come close enough to deflect the orbit of asteroids in outer solar system, potentially towards the Earth.
