Wsn't it solved long ago? There's even an old KSP mod 'Pricipia' for it.

You can simulate a specific arrangement of n-bodies, where n > 2. Depending on how accurate you want it to be, you may need a supercomputer.

If n = 2, then you can work it out on a napkin. If n = 1, you can draw a circle, point at it, and say "I figured it out!"

So they mean there's no general solution. That doesn't mean that we can't find specific solutions.

As for your notion of solved, that's solved in a numerical sense.
