It is actually difficult to determine the distance to black holes, but a nearby object believed to be a black hole from observations of strong X-ray emission is Cygnus X-1, located about 8000 light years away. Cyg X-1 is an ordinary star that is believed to be orbiting a black hole.
No black hole has "eaten" Pluto.
No. Pluto is nowhere near massive enough to become a black hole.
No, Pluto has not been sucked up by a black hole. Pluto is a dwarf planet located in our solar system, while black holes are distant cosmic phenomena with intense gravitational pull. Pluto orbits the Sun and is not at risk of being sucked up by a black hole.
The closest known black hole is at a distance of about 3000 light-years. And no, there is no immediate risk.
Pluto has not become a black hole. Pluto is a dwarf planet located in our solar system, while black holes are objects formed from the remnants of massive stars that have collapsed under their own gravity.
There are no known planets in the vicinity of a black hole.
False. Nothing actually happened to Pluto itself. All that has happened is that, after discovering several new Pluto-like objects, scentists came up with a new definition for a planet that excluded Pluto.
About as far as Earth or the Sun is.
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.
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.
I believe the closest black hole is in the center of the Milky Way galaxy... But is a black hole a dark hole? Hmm.
In April 2008 NASA discovered the smallest black hole ever. The black hole, called XTE J1650-500, is15 miles across. It is located in Ara, a constellation in the Milky Way Galaxy.
