So I recently found out that a star known as Gliese710 is heading towards the solar system. It will arive in the next 1 million years. Why does it pose a threat to us? Because it might be headed towards the inner solar system! You know, where Earth orbits the sun. Earth might be ejected out of the solar system, if it luckily isn't, then it's orbit gets modified like, a LOT.
