What is the pulling force of a black hole?
(Grades 5-8) series. A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space.
How far away is the black hole in our galaxy?
1,500 light years away
Very few black holes of this mass have been found in the universe. This black hole is 1,500 light years away from Earth, still inside the Milky Way galaxy.
How strong is the black hole in the Milky Way?
The largest supermassive black hole in the Milky Way’s vicinity appears to be that of Messier 87 (i.e. M87*), at a mass of (6.4±0.5)×109 (c. 6.4 billion) M ☉ at a distance of 53.5 million light-years.
How far away is Sagittarius A from Earth?
25,640 light years
Sagittarius A*/Distance to Earth
Is there a black hole at the center of every galaxy?
Scientific evidence suggests that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a ball with a diameter about the size of the sun.
How is a supermassive black hole formed?
Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.
What is the size of a medium-sized black hole?
The most common type of medium-sized black holes is called “stellar.” The mass of a stellar black hole can be up to 20 times greater than the mass of the sun and can fit inside a ball with a diameter of about 10 miles.
What kind of black hole is a single atom?
The black hole’s mass and size determine what kind it is. The smallest ones are known as primordial black holes. Scientists believe this type of black hole is as small as a single atom but with the mass of a large mountain.
