n-body problem. Look it up.

There is no single mathematical solution (even in relativistic gravitation) to this problem of wobbly orbits.

This is just one of the many.

We need real measurable and verified repeatable observation, and who's going to give it to us? NASA?

So, there's something something somewhere out there.

Where? How far? What orbit? Will it cross? We don't know.

We will see, when we will see, if we get to see.
