A planet that falls into a black hole would get completely destroyed. Its mass would be added to the mass of the black hole.
They get destroyed. Their matter becomes part of the black hole.
We have seem evidence of objects falling into black holes, but most of what we have seen is probably gas. We do not know of any planets that have falledn into black holes.
Stars can be sucked into black holes.
There are no black holes anywhere near Earth, so no we won't get sucked into one.
Stars do get sucked into a black hole if they pass the event horizon.
Yes
no, it just gets sucked into it
Anything that gets close enough.
Anything and anyone that ventures too close to a black hole can be pulled into it.
well the clouds get sucked in
There are hypotheses about so called 'virtual particles' that may travel faster than speed of light, and hence are not sucked up by Black Holes. Also, Black Holes cannot suck another bigger Black Hole, when they meet a bigger one, they get sucked up rather.
The orbits of the planets around the sun is a good example. The planets are constantly circling the sun. Black holes are probably the most massive and awesome example of gravity. They cannot be seen, but the way stars and light move around black holes, we know that they are there. The Swarz Child Radius is the radial distance where light can't escape from a black hole. It is the perimeter surrounding a black hole and if anything including light goes inside that perimeter, it will be sucked in by the black holes gravity.
