 Unfortunately predicting the potential influences of these extrasolar objects is even more difficult than predicting the influences of objects within the system simply because of the sheer distances involved.Among the known objects with a potential to significantly impact the Solar System is the star Gliese 710, which is expected to pass near the system in approximately 1.281 million years.Though the star is not expected to substantially affect the orbits of the major planets, it could substantially disrupt the Oort cloud which could cause major comet activity throughout the solar system.
