There is simply no way of knowing this. Once matter is consumed into a black hole, it is converted into gravitational energy; a black hole's contents cannot be dissected and catalogued. However, according to an idea called the holographic principle, it may be possible for all the information contained within a black hole is encoded on its surface. If this proves to be true, then it might be possible to determine everything that has been sucked into the black hole.
We do not know of any planets that have been destroyed by a black hole, but it probably has happened. Because of the vast distances in space and the fact that neither planets nor black holes emit light, both are hard to detect.
You will see stars/planets orbiting what looks like nothing.
Such a black hole is never found, but theoretically it should be possible. If the planets are far enough from the black hole where they circle around they will just orbit the black hole in the same way as they would orbit a star with the same mass if it would replace the black hole. But if it exists it would be very hard to detect, exoplanets are detected because of their interaction with their mother star(They block some light and have gravitational influence that can be detectable), for black holes that is not an option because they are obviously black. The planets themselves won't emit light so there is no way we can detect such a system if it exists.
The nearest known black hole is at a distance of about 3000 light-years. I don't think any nearby planets are known - most known planets are closer than that, and if any planet is known at a distance of 3000 light-years, it is unlikely to be anywhere near such a black hole.
Nothing man-made has been sent to a black hole, the furthest out one of our probes has got is the edge of our solar system. A probe would have to go many orders of magnitude further than that to get to a black hole.
no
There are no known planets in the vicinity of a black hole.
A black hole
They are unrelated.
Some stars, comets, stardust, moons, planets, have been "eaten" by a black hole. None know for sure how many of each.
As the planet is approaching a black hole due to the immense gravitational pull on the objects surrounding it, the planet revolves around the black hole until it falls into the black hole.
A planet that falls into a black hole would get completely destroyed. Its mass would be added to the mass of the black hole.
I don't think there would be planets, but I know there are stars!
there is nothing inside a black hole...a black hole's density is very large...so large all of our planets and stars including the sun's density would not even be 0.1% that of a black hole...a black hole is so strong, not even light can escape it...nothing can.
