Could our planet orbit a blackhole without it being destroyed for a couple of years?
For example, say a black hole entered our solar system and pulled us into its orbit, would it destroy us immediately or would we orbit it until we fell in?

tidal forces would DESTROY us

How badly? Super volcanoes and such?

maybe they'd destroy you, you little bitch

there's nothing special about a black hole, the attraction law is the same as any other thing
Jaxson Cook
That depends on a number of things.
For example. if our Sun was replaced with a black hole of the same mass instantly, it would have no affect on our orbit.
However, you said a black hole entering our solar system, so that's going to depend on mass, where it enters, the path, where Earth is in relation to it, etc
It's too broad a question.

Say it has a similar orbit to Jupiter, when it enters

What would happen if a black hole collided with Uranus?
Liam Rogers
Since you stated in the OP that Earth would orbit the black hole, I'm assuming it will have a larger mass than Earth.
I think any object with that mass entering the solar system around Jupiter's orbit would wreak havoc on the inner planets by perturbing their orbits.

>say a black hole entered our solar system
ok well we have no evidence that primordial black holes exist, so we'd be talking about something on the scale of 3 solar masses or higher. this would completely disrupt all planetary orbits and even gravitationally dominate the sun itself. there probably isn't any single trajectory that would produce a stable earth orbit, and would lead to either a collision or ejection from the solar system.

Would it immediately swallow up the Earth though? Or would it orbit the black hole?

No.
> Or would it orbit the black hole?
Unlikely.

Jackson Bennett
more like it plows right through, causes the sun to wobble a good bit, slingshots past one of the gas giants, and its gravity slings most of the terrestrial bodies out into the void or into the sun
not good
Brandon Flores
On our orbit.

There's plenty of stat that share orbits with black holes. They're not particularly rare or particularly dangerous. Yes if something smaller got to close it would get sucked in but the same applies to all stars. They might have infinite density but that's not the same thing is infinite mass
Josiah Butler
The radiation would fry us.

No one cares about that.

That's actually more interesting than I thought. It would sling shot all our planets out of orbit
