By the time it was shifting planetary orbits, it would be on top of us compared to anything else in the galaxy. So if it was speeding toward us from an empty area of the sky, while not getting close enough to other stars to give away its presence easily, we might not realize it until very late.

What would we do anyway? Take photos I guess.

Send some drillers to set explosives on it.

We could throw all the garbage into it, solve the landfill problem.

It's hard to think that from a far enough distance, it would give us more than a few centuries notice atleast?

I feel like if there was, even a sun mass object, within the oort cloud, we would 1000000% know it. So if a 12x mass black hole was moving towards us, surely we'd be able to detect it. When I say shifting orbits, I'm saying very marginally, not enough of a difference, but enough to be detected to where we know something big is headed toward us.

Jupiter has a very noticeable effect on the sun, and the sun is like, 99.8% of the solar systems mass. Surely a 12x black hole would affect something enough for us to detect. Our planets/sun would surely feel it from very far away, and Im sure we would be able to detect the increasing shift due to the black hole heading towards us
