You can get as close as you want, as long as your tangential speed is high enough
to maintain an orbit. Inside of some distance, that'll require the speed of light (or
more). The distance depends on the mass of the black hole.
You will always be effected by any mass because gravitational fields are infinite. But being substantionally effected by a black hole depends on how massive the black hole is.
There is one that is about 7,800 light-years from Earth. There is also another one that is in the center of our galaxy which is about 26,000 light year away.
Not directly. If large amounts of matter is falling into the black hole it will heat up and glow brightly. You could also potentially see the distortion of light around the black hole, but you'd have to get pretty close to see that.
A quasar is believed to have a supermassive black hole at its center. The radiation is emitted outside the black hole's event horizon - from matter that is falling into the black hole.
A quasar is a disk of superheated material falling into a supermassive black hole. The radiation from a quasar is so intense that it actually pushes matter away from the black hole, preventing it from falling in. This process limits how fast a black hole can grow.
Upon falling towards a black hole the "front" is pulled more than the "back" causing objects to stretch.
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
You would die quickly, either before, or after, falling into the black hole, depending on the mass of the black hole.

If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.

yes.

if you get to close
No. Earth would be destroyed if a black hole came anywhere close to it.
Objects which approach a black hole will get sucked into it.

That seems likely, considering the large number of black holes and of planets in the Universe. However, I am not aware of any specific observation of a planet falling into a black hole, for example. On the other hand, the likelyhood of a black hole getting close to Earth, withint any reasonable amount of time, is very low.
Particles falling into a black hole release a large amount of x-rays as they do so. This is not energy from the black hole itself, but energy release that is a sign of a black hole.
