  There have been very many false alarms about distant planets in the solar system but maybe they really are on to something this time.

  What fantastic news and from our own solar system too! Thanks for posting. The Caltech video is also worth watching, I think. Planet-9's possible period is some 10,000-20,000 years??? Whew, the mind boggles. 😃
