New evidence found for Planet 9

Quote

A small team of planetary scientists from the California Institute of Technology, Université Côte d'Azur and Southwest Research Institute reports possible new evidence of Planet 9. They have published their paper on the arXiv preprint server, and it has been accepted for publication in The Astrophysical Journal Letters.

In 2015, a pair of astronomers at Caltech found several objects bunched together beyond Neptune's orbit, near the edge of the solar system. The bunching, they theorized, was due to the pull of gravity from an unknown planet—one that later came to be called Planet 9.

So there's another planetoid out in the Kuiper Belt?  Should we be perturbed?

The word planetoid has been used only by you, there is a very good reason for that, it's because the article is about a PLANET not a planetoid. Planetoid is another word for asteroid. I suspect the term you were groping for is dwarf planet, but this isn't about dwarf planets either.

If Planet 9 exists it is hypothesised to be 5 to 10 times greater in mass than the Earth.

What personally perturbs you is your own business.

Which would answer the question where is our system's super Earths/ mini Neptunes. Theoretically we should have one which Jupiter pushed somewhere.

I try to avoid politics myself except to mock a 21st C. Torie now and then.

If scientists are able to detect planets around distant solar system how are they not able to find a planet in our own solar system? Maybe an expert could enlighten me.

Sometimes is easier to observe things in the distance as you can see the whole "picture" than observing yourself in the picture.

The "transit method" where they watch it crossing the front of the star.

It's far too small.

It will be equipped, they note, to search in new ways for the planet in a rigorous assessment of its existence.

What 'new ways'?
