The mass of the black hole in Sgr A* is estimated at approximately 4 million solar masses (see related links).
Assuming its rate of rotation is sufficiently small, we can estimate its Schwarzschild radius R, i.e. the radius of the event horizon, using the following formula from General Relativity:
R = 2GM / c2
where G is the gravitational constant and c is the speed of light. M is simply the mass mentioned above.
This gives a radius of approximately R = 1010 m, which is very roughly a tenth of the distance between the Earth and the Sun.
What else can I help you with?
Nothing can escape this including light?
A black hole has an 'event horizon'. The event horizon is the threshold at which point there are no longer any paths leading away from the center of the black hole. This means that the gravitational forces are so strong that nothing can escape their pull once past the event horizon, including light energy.
How far away is the black hole in the centre of your galaxy?
The black hole at the center of our galaxy, the Milky Way, is about 26,000 light-years away from Earth. It is known as Sagittarius A* and has a mass equivalent to about 4 million times that of our sun.
For an outside observer what happens to time at the event horizon?
Time stops when you're in a black hole because you die. Actually, time stops in Black Holes because a Black Hole does not follow the Space- Time Continuum, and a Black Hole is a singularity, that has zero volume, and infinite density.
Can a super heated quasar escape a black hole?
No, a superheated quasar cannot escape a black hole. Quasars are extremely bright and energetic sources powered by accretion onto supermassive black holes, and their emissions arise from the material falling into the black hole. Once matter crosses the event horizon – the point of no return – it cannot escape the black hole, including the energy emitted by the quasar.
Why does horizon move away if you go closer to it?
The horizon appears to move away as you approach it due to the curvature of the Earth. As you get closer to the horizon, you are able to see farther around the curve of the Earth, causing it to appear as though it is moving further away. This effect is more noticeable in flat, open landscapes.
How does a quasar burst away from a black hole if the black hole has infinite gravity?
It's only infinite around the event horizon.
How many light years away from earth is galactic center?
The galactic center, where the supermassive black hole Sagittarius A* is located, is approximately 26,000 light-years away from Earth. This region lies in the constellation Sagittarius and is surrounded by dense clouds of gas and dust that obstruct visible light observations.
Nothing can escape this including light?
A black hole has an 'event horizon'. The event horizon is the threshold at which point there are no longer any paths leading away from the center of the black hole. This means that the gravitational forces are so strong that nothing can escape their pull once past the event horizon, including light energy.
What is the distance of the constellation Sagittarius from earth?
1.2Light Years away to be exact.
How far away are clouds on the horizon from a viewer's perspective?
Clouds on the horizon appear to be about 2 to 3 miles away from a viewer's perspective.
How far is horizon at 100 ft?
At 100ft, the horizon is approx 12 miles away.
What is the importance of the horizon?
The horizon is point at which the earth curves away from our line of sight at the earth's surface.
Why do you have horizon?
Because the earth is a sphere. The horizon is the curvature of the earth (or other planet) as it falls away from you.
Can sound escape a black hole?
No. Nothing can escape a black one it crosses the event horizon. In most cases a black hole is in the vacuum of space, which cannot carry sound. Matter falling into a black hole will reach incredible speeds, potentially approaching the speed of light, so sound could not move though that matter, even away from the event horizon.
How far away is the black hole in the centre of your galaxy?
The black hole at the center of our galaxy, the Milky Way, is about 26,000 light-years away from Earth. It is known as Sagittarius A* and has a mass equivalent to about 4 million times that of our sun.
Why doesn't someone enter a black hole?
Because there are far easier ways to commit suicide. 1. The closest black holes are too far away to reach in an entire lifetime, even if you were traveling at the speed of light. 2. No one knows for sure what lies beyond the event horizon of a black hole, but they do know that once something passes the event horizon of a black hole, it is impossible for it to escape the same way. Even if the person that entered the black hole did survive and was able to see a black hole beyond the event horizon, they would have no way to pass this information on to other people. 3. Tidal forces would rip a person to shreds long before reaching the event horizon anyway.
For an outside observer what happens to time at the event horizon?
Time stops when you're in a black hole because you die. Actually, time stops in Black Holes because a Black Hole does not follow the Space- Time Continuum, and a Black Hole is a singularity, that has zero volume, and infinite density.
