What is the nearest black hole to the earth?
For a comparison, Sagittarius A, the supermassive black hole at the center of the Milky Way, is thought to be about 4 million times the mass of the sun. In addition to being among the smallest black holes ever seen, it’s the nearest one to us that we know of, at just 1,500 light years away.
How long would it take to get to the nearest black hole?
So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.
How is it possible for scientists to study black holes?
Scientists can’t directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby.
How big is Sagittarius A *?

How far is the farthest black hole?
This black hole is 1,500 light years away from Earth, still inside the Milky Way galaxy.
How many stars are in 10 light years?
As of October 2012, astronomers have been able to detect planets in the Solar System and around Alpha Centauri B and Lalande 21185 among the nearest 12 stars….Stars within 10 light-years.

What does light years away mean?
Definition of light-years away : very far away in time A cure for that disease is still probably light-years away.

What type of black hole is Sagittarius A?
supermassive black hole
Based on mass and increasingly precise radius limits, astronomers have concluded that Sagittarius A* is the Milky Way’s central supermassive black hole. The current value of its mass is slightly in excess of 4 million solar masses.
What is the closest black hole we know of?
The closest black hole we know of is V616 Monocerotis, also known as V616 Mon. It’s located about 3,000 light years away, and has between 9-13 times the mass of the Sun. We know it’s there because…
Will the Earth be pulled into the Milky Way’s black hole?
There is no danger of the Earth (located 26,000 light years away from the Milky Way’s black hole) being pulled in. Future galaxy collisions will cause black holes to grow in size, for example by merging of two black holes.
Is it possible to escape a black hole?
So… there’s no escape. Get too close to the black hole and you’ll be compressed beyond comprehension, perhaps into an infinitely small point. But you can be reasonably distant from a black hole too, and still have your day ruined. A black hole reaches out through the light years with its gravity.
How long does it take for a black hole to form?
It can take less than a billion years for one to reach a very large size, but it is unknown how long it takes them to form, generally. Scientists obtained the first image of a black hole, seen here, using Event Horizon Telescope observations of the center of the galaxy M87.
