Don't worry, it's only a rogue black hole:

but as the comments noted, where is it heading?

Hi Mark, given that it was kicked out of another galaxy, even if it was headed for us, the human race wouldn't even be a vague memory by that time, our sun would only be a core of itself and a relatively cool core at that.  Jan

Core--pun

as Jan said there is nothing to worry aboutThere is also article at universetoday.com

I wasn't worried, as the info was detailed on that point. I was wondering where it was headed and if we could observe its travel.

What's more worrisome is if a rogue gamma burst is heading our way.

Mark

yeah, gamma ray bursts are pretty dangerousand rogue ones even more :D

Yes, it would be a bit of a downer if either event were to transpire. A more
local (but highly unlikely outcome) risk is that the Large Hadron Collider
might create a stable black hole when activated this year. If that were to
happen, I wonder how long it would take to devour the earth?

LHC generating black holes is neatWe'll see when they activate it :D

I don't think it would be too neat.  I don't think I would make a good string of spaghetti or infinitely dense (no jokes here) particle
