Researchers determined that the black hole V404 Cygni (Nova Cygni 1989, GS 2023+338) is the closest at approximately 7,800 light-years (or 2400 parsecs) from Earth, in the constellation Cygnus. It is measured to have a diameter of roughly 37-56 miles (60-90 km) and is 10 to 15 times the mass of Earth's Sun.
The closest known black hole (others that are closer to us may still be discovered) is at a distance of 3000 light-years. Its mass is estimated to be about 11 solar masses.
The closest known black hole is at a distance of about 3000 light-years. And no, there is no immediate risk.
The closest black hole from Earth is V4641 Sgr, which is 1,600 light-years (100,000,000 AU) away.
The closest known black hole is at a distance of about 3000 light-years; it seems likely that black holes closer than this will be found eventually.
Neptune does not have a black hole

Neptune does not have a black hole
I believe the closest black hole is in the center of the Milky Way galaxy... But is a black hole a dark hole? Hmm.
No. No black hole is big enough to do that.
Actually one interpretation of the big bang is as a white hole, the inverse of a black hole.
It seems that the closest known black hole is at a distance of about 3000 light-years.
A black hole can,but it is very rare for a black hole big enough to swallow Earth.
Any matter that gets close enough to a black hole can be absorbed by it. But there are no known black holes nearby - the closest known black hole is at a distance of 3000 light-years.
