Star Will Have ‘Close Encounter’ With Sun in 1 Million + Years

ESA’s Gaia satellite has tracked the the motion of the star Gliese 710. The trajectory that was calculated from the motion has the star coming within 16,000 Earth-Sun distances in about 1.3 million years. As a result, Oort Cloud-residing comets could get a push into a new orbit by Gliese 710's gravity, eventually sending some of them into the inner solar system.
