A mysterious Mars-sized planet may be hiding at the edge of our solar system

Why is it mysterious and why did it take so long to 'discover'? Where's the rove orrrr, when's the rover? We have the time, technology. We should be discovering everything possible.

Like I have been stating, over and over, we will soon find out that our solar system has a binary companion. A failed star that is keeping planet 9, and other objects that are ETNOs in their long elongated orbits.

The Caltech scientists are stating that there is a 1% -2% chance that this is a fluke in the data. This means that the planet most probably does exist.

What does a "failed star binary companion to the Sun" have to do with a suspected Mars sized planet beyond the Kuiper Belt? They are two completely different things. One (the latter) is a very real possibility, and the other is almost certainly pure fantasy.

Nothing's been discovered (at least yet). "Mysterious" is just a clickbaity word, to attract attention.
