I wonder if this new planet would be concealed on the back side of the sun where we are never able to see it.Even with the Hubble Space telescope.

You would think that with a telescope that powerful we would have seen it by now.

Given that the article says P9's orbit is about 10-20,000 Earth years, we would be in a position to see it at some point during our year.
