Physically, a black hole has no length, width, height, radius, diameter, or size of any kind.
But it can have millions or billions of times as much mass as the sun has, and
its gravitational effects can be felt over a region of space larger than the solar
system.
First of all, our sun can not become a black hole, it is too small for that. However if a star is three times bigger than our sun, then yes it will become a black hole.
Black holes can be many different sizes. Therefore, there are some black holes that are bigger than the sun, and there are some that are smaller than the sun.
Simply put, it isn't big enough. A star must have a certain mass to become a black hole after its "death", and the Sun doesn't have enough. Our "Sun" is not big enough, only stars that are a lot bigger will explode and become a black hole.
No. There not a black hole on the sun or on Jupiter.
Black Hole Sun was created in 1994-05.
The sun's energy has not formed a black hole.
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
It doesn't "need to live", but it will, whether it needs, or not. A black hole with the mass of our Sun or more is very resilient; it will continue existing - as a black hole - for much, much longer than the current age of the Universe.
A black hole has a much larger mass than a planet. The mass of a black hole, however, is contained in a point that is smaller than some fundamental particles. The event horizon of a typical stellar mass black hole is much smaller than any planet, but the event horizons of supermassive black holes are much larger.
In theory, yes, a black hole could suck up the sun.
The black hole is estimated to be about 3.5 billion times the mass of the sun.
A black hole is a region in space where gravity is so strong that nothing, not even light, can escape from it. The size of a black hole is determined by its mass, with smaller black holes being about the size of a city and larger ones being millions of times bigger than our sun. Compared to other celestial objects in the universe, black holes can be much smaller or much larger, depending on their mass.
