I come from 2039.
Scientists have discovered 8 more planets like Planet X and Neptune and expect many more, so the IAU has decided to remove all of them from the list of planets and return to the seven traditional planets model (requiring naked eye observation) so that astronomy is not too hard for kids in school.
