It also makes you realize that, if a black hole appeared anywhere close to our solar system, we are screwed (unless nuking black holes works).
Here's something that I'll add to the common misconceptions thread.

Black holes are not magic vaccuum cleaners. If faraway giant star does not have enough mass right now to suck in the earth, then it will still not have enough mass to suck in the earth when it collapses.

If the sun somehow turned into a black hole with the exact same mass, none of the planets would be sucked in. The orbits would be almost the exact same.
