About 30 kilometers in diameter. This refers to the "event horizon". Actually this diameter is directly proportional to the mass: at twice the mass, a black hole will have twice the diameter.
Stellar black holes have been found with estimated diameters from about 20 kilometers upwards.

What will Antares die as?
Antares is a red supergiant and has enough mass to explode as a supernova and then collapse into a black hole.
What happens star's furnace stops?
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
What would happen if you jumped into a Kerr black hole?
If you jumped into an "ordinary" Schwarzschild black hole, you would be crushed into a long line of particles, which means death by a black hole. If you jumped into a Kerr black hole, the same process may occur, but the only thing different is that a Kerr black hole spins, and a Schwarzschild black hole does not. That answer needs a bit more detail. Please use the "related link" below.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

What would happen if a black hole sucks up beetle juice and blew up?
I'm not sure, though I hypothesize that the explosion would be contained in the gravity of the black hole.
What effect will be there on rotation of the earth if sun collapse to black hole?
If the Sun were to collapse into a black hole, its mass would remain the same, so the Earth's orbit and rotation around the black hole would continue as normal. However, without the Sun's light and heat, the Earth would quickly cool down and life would cease to exist.
What would happen if Earth's gravity was a billion times stronger than a black hole's gravity?
If Earth's gravity was a billion times stronger than a black hole's, everything on Earth would be crushed instantly under the immense gravitational force. The planet itself would collapse into a black hole due to the overwhelming gravity. Life as we know it would cease to exist.
When a black hole collaspes does its mass decrease?
As far as we know, black holes cannot collapse any further. However, if a star were to collapse and form a black hole, its mass would be the same.
Does the earth have a black hole?
No. Earth would be destroyed if a black hole came anywhere close to it.
What will happen to are earth in a black hole?
Should Earth ever collide with a black hole, it would get destroyed.
What if a black hole forms by earth?
Black hole formation can not be surreptitiously initiated just anywhere in outer space. Theoretically black holes were formed upon the onset of the Big Bang or can form upon the gravitational collapse of a star of about 3-4 solar masses.
Would one cubic light year of water form a black hole?
No, one cubic light year of water would not form a black hole because the mass of the water would not be dense enough to collapse into a black hole. The density of water is much lower than what is required for a black hole to form.
Sometimes the leftovers of a supernova collapse to from a?
A black hole or a neutron star.
What do black holes result from?
Usually from the collapse of a massive star. It isn't quite clear how a supermassive black hole is created; it is possible that it also starts as a stellar black hole (a hole resulting from the collapse of a star), but it isn't quite clear how such a black hole can get so huge in a relatively short time.Usually from the collapse of a massive star.

What would happen if a black hole came to earth?
Nothing, not even light, can escape a black hole. So Earth would get caught into the black hole's path and we would be sucked up and crushed to oblivion
Can you see a black hole when you are on eath?
You cannot see a black hole when you are on Earth, unless a black hole were to absorb Earth, which even then, you would see it in a split-second before it would engulf you
What effects would a black hole do to your earth?
My Earth, as well as my Sun, would be completely destroyed if a black hole came through our Solar System. I'm not certain what would happen to YOUR Earth.
