How big is a black hole in KM?
But, as the channel’s narrator notes, that black hole is only 17.2 kilometers—or roughly 10 miles—wide. From there, the comparison bounds up to black holes that have hundreds of times the mass of the Sun.
What is the depth of a black hole?
In the case of a black hole, depth has no meaning. That is because by definition, all black holes cause a disturbance in the space-time continuum. First of all, there is a point called the “even horizon” past which nothing can be seen.
What is the smallest radius of a black hole?
EDIT: I’d also like to add that the theoretical minimum mass for a black hole is the Planck mass, 2.2×10−8 kg, which would yield a radius of 3.267×10−35 meters, though these would not be formed by stellar collapse, though they could have formed as primordial black holes in the very early universe.
How much does a black hole weigh in kg?
This is a very large number, about 2 x 10^30 kilograms. That’s 2 with 30 zeroes after it, or written out: 2,000,000,000,000,000,000,000,000,000,000. This is about one million times more than the mass of the Earth. A stellar black hole forms when a massive star undergoes an explosive death called a supernova.
Would Earth become a black hole?
After just a few minutes more — 21 to 22 minutes total — the entire mass of the Earth would have collapsed into a black hole just 1.75 centimeters (0.69”) in diameter: the inevitable result of an Earth’s mass worth of material collapsing into a black hole. When matter collapses, it can inevitably form a black hole.
Will Earth become a black hole?
Theoretically yes, but practically it would be impossible to create a penny-sized black hole here on Earth. Forming a penny-sized black hole on Earth would take a huge amount of mass and a method of condensing that mass into a tiny area. In addition, the closest known black hole to Earth is 1,000 light-years away.
Can you see TON 618 from Earth?
The light originating from the quasar is estimated to be 10.8 billion years old. Due to the brilliance of the central quasar, the surrounding galaxy is outshined by it and hence is not visible from Earth.
