Planet Nine may exist, but it might be hiding behind Neptune

Evidence for Planet Nine continues to mount, but there may be a good reason why scientists have yet to find it  - it may be hiding. In October 2017, NASA released a statement saying that Planet Nine may be 20 times further from the Sun than Neptune is, going so far as to say "it is now harder to imagine our solar system without a Planet Nine than with one."
