This one. not ten. but 20 thousand years. Assuming they did their math right.
Their math says nothing about where it is in its alleged orbit however. It clearly is not something you will see even with hubble, it will take a scope with a lot more mirror than that to suss it out. And it would have to be covered with some kind of ice, a nice reflective surface to be visible at all.
It will be a great discovery if they ever find it.
