It would be the same effect as a star of the same mass coming within the same distance.
One billion miles is 10.75 times the distance of the the earth to the sun. Since the force of gravity declines with the square of distance, and black holes are typically about 3-5 solar masses, the force of gravity would equal about 2.5% to 4.3% of that of the sun on the earth. Enough to nudge our orbit, and maybe mess with our seasons a bit, but I think we would have a good chance of surviving.

It all depends on the size of the black hole and how fast it is going. For one with the mass a couple of times that of the sun and going at a typical rate for stars in our area of the galaxy, the main effects would be changes in the orbits of the planets. The ones further out like Saturn, Uranus, and Neptune would probably be flung out of the system. How it would effect earth would depend on exactly where earth is in its orbit. The most likely scenario would be that the orbit around the sun would become more elliptical, which could have some effects on our seasons depending on just how distorted the orbit was.

Well, if it was the supermassive black hole believed to be at the centre of the galaxy - that is 3 billion miles across so the Sun would be already in it.

Unless it were a micro black hole (left over from the Big Bang), we wouldn't be around to see what happened. It would disrupt the orbits of the planets and possibly destroy the sun.

I think that would depend on how massive the black hole was. The planets' orbits might be disrupted, and matter might flow into the black hole from the sun. I wouldn't wanna be nearby, that's for sure.

black holes are shaped even as a huge call is to particular to blow up as a supernova. even as the ability runs out gravity takes over and it starts to callopse. the technique is quick and the great call turns into smaller. because it does the get away speed turns into denser and reaches three hundred, 000 km (186,000 mph) it really is the speed of sunshine really user-friendly cant get away. to respond to your question the mass of our planet might want to rip aside and by no ability something might want to exist.

Depends on the size of the black hole...

it would slowly pull everything into it. basically the end of everything.

nothing. has to be closer before it can cause any problems.
