What is the closest known black hole to Earth?
To make it easier to compare distances, our nearest star aside from the Sun – Proxima Centauri – is about 4.24 light years away and our Milky Way galaxy is approximately 100,000 light years in diameter.
Where are black holes located on Earth?
Black holes are a class of astronomical object that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, not even light. Observational evidence indicates that nearly all large galaxies contain a supermassive black hole, located at the galaxy’s center.
How many black holes are on earth?
Estimated at 40 billion solar masses.) APM 08279+5255 (contains one of the largest black holes estimated at 23 billion solar masses.
Can you see a black hole?
A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.
