Nobody has ever visited a black hole. The nearest known black hole is many light years away. Much to far away for us to reach it.
The black hole at the center of our galaxy, the Milky Way, is about 26,000 light-years away from Earth. It is known as Sagittarius A* and has a mass equivalent to about 4 million times that of our sun.
No. The black hole at the center of the galaxy is too far away to affect earth.
The nearest known black hole is at a distance of about 3000 light-years - so it is far away from the Solar System.
The closest known black hole to Earth is about 1,000 light-years away in the constellation of Monoceros. It is known as V616 Monocerotis or A0620-00. It is a stellar-mass black hole formed from the remnants of a massive star.
There are many black holes in the universe .Scientists believe that there might be a black hole in the centre of our Milky Way galaxy which is about 25,000 light years from earth, and that that is why it rotates about its axis.
No, it is not possible for an astronaut to be sucked into a black hole. Black holes are extremely far away and astronauts do not travel close enough to them. Additionally, the gravitational pull of a black hole is so strong that no known force or technology could overcome it.
No. The nearest black holes to Earth are many light years away, much to far to affect us.
No known person has been through a black hole. The nearest known stable (stellar mass) black hole is too far away for us to reach with our current technology, and an encounter with one would almost certainly be fatal.
About as far as Earth or the Sun is.
the answer is 738,000
A black hole can be located due to its gravitational attraction. If matter falls into the black hole, it will emit x-rays; also, even if this is not the case, the black hole can be detected by the gravitation it exerts on nearby objects - for example, if an object orbits the black hole. A black hole may also change the direction of light emitted from behind it, for example, from a far-away star or galaxy. This is known as "gravitational lensing".
