Black holes must have a mass how many or more times the mass of the sun?

Black holes are just a singularity and are thus very small, much smaller in fact than our sun. However, the event horizon (point of no return) can extend much farther in radius than our sun. A stellar mass black hole has an event horizon only a few kilometers across, much smaller than the sun. A supermassive black hole, with a mass millions to billions times that of the sun may have an event horizon far larger than the sun. Lastly, all black holes are many times more massive (amount of mass in them) than our sun. This is because they are all created by suns many times bigger than our own.

∙ 10y agoThe evidence is fairly abundant particularly where active galactic nuclei are concerned. For example, a recent study at specific frequencies of our own galactic center yeilded data about the orbital path and speed of stars near the core, and constituted compelling evidence that a black hole had to be present of over four million solar masses. But such is also true of other galaxies - similar calculations yielded a mass of 100-200 million solar masses in the nucleus of the Andromeda galaxy (see also the m-sigma relation).

∙ 12y agothere are many different sizes of black holes, but they are all the same. Some black holes are the size of Golf balls, some, lie the ones in the center of galaxies, are called supermassive black holes and can be up to 10 billion times the size of the sun

What is an intermediate black hole?
An intermediate-mass black hole is one that has a mass somewhere between 100 and a million solar masses, i.e., larger than the stellar black holes, but smaller than the supermassive black holes. It seems likely that such holes should exist, but the observational evidence is not yet very firm.An intermediate black hole is one whose mass is somewhere between that of a stellar black hole (a few times the mass of the Sun), and that of a supermassive, or galactic, black hole (millions or billions of times the mass of the Sun).
Is black holes bigger than galaxies?
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.
Can a black hole be as big as a human?
Technically yes, realistically, probably not. The best measure of the size of a black hole is the size of the event horizon. That we know of, black holes fall into two general categories: stellar mass black holes and supermassive black holes. The diameter of the event horizon is directly proportional to the mass. Stellar mass black holes range in mass from about 3 to 30 times the mass of the sun, with diameters several miles to several tens of miles. Supermassive black holes are millions to billions times the mass of the sun and are millions to billions of miles across. A black hole with roughly the mass of Saturn would have an event horizon about as wide as an adult human is tall, but there is no known way for an object of that mass to become a black hole.
What is the most common form of black holes in the universe?
Probably stellar mass black holes
How do black holes survive?
it's mass
How many times greater is a black hole mass than the sun?
The masses of black holes vary greatly. The lowest mass stellar black holes are about 3 times the mass of the sun. The most massive black holes are about 12 billion times the sun's mass.
Is a black hole just a hole in space that contains no matter?
No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

How are supermassive black holes different from stellar mass black holes?
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
How does a black holes acquire greatest mass?
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.

Is the Earth bigger than a Black hole?
It depends on the mass of the black hole. The size of the event horizon is directly proportional to mass. Most black holes are what we call "stellar mass" black holes which range from about 3 times to 30 times the mass of the sun. The event horizon of a 30 solar mass black hole would be about 110 miles in diameter. Earth, by comparison, is just over 7,900 miles in diameter. An intermediate mass black hole about 1,340 times the mass of the sun would have an event horizon about the same size as Earth. Astronomers have detected supermassive black holes up to 12 billion times the mass of the sun. Such a black hole would have an event horizon 44 billion miles across, or about 5 times larger than the orbit of Pluto.
What is the catastrophic distance between black holes and stars?
That would depend a lot on the mass of the black hole. For example, a stellar-size black hole, say, 5 times the mass of the Sun, would of course have the same gravitational attraction as a star that has 5 times the mass of the Sun. But there are larger black holes, too - those at the center of galaxies have masses millions, or even billions, times the mass of our Sun.That would depend a lot on the mass of the black hole.

Is a black hole massive?
A black hole can have anywhere from 2-3 times the mass of the Sun (the lower limit for a stellar black hole), to about 20 billion times the mass of the Sun (the largest known supermassive black holes).
How small can black holes get?
A star that stops producing radiation, with a mass about 2-3 times the mass of our Sun (mass remaining after a possible supernova explosion), or more, can become a black hole. There is also some speculation about miniature black holes ("primordial black holes"), with much less mass than that, which might have formed during the Big Bang, because of the enormous density that existed at that time. However, so far there is no evidence that such black holes actually exist.
What has a lot of mass?
Black holes.
