They're some of the most violent objects in our universe,

powerful enough to rip entire stars to pieces.

You see, the more mass you can shrink into a small space,

the stronger your gravitational force will become.

To make Earth into a black hole, for instance,

you'd have to shrink it to less than an inch across.

But real black holes are much larger than that

Here's just how big black holes can really get.

There are three common types of black holes.

and collapses in on itself, like this one,

roughly three times the length of Manhattan.

there's a black hole that is 58 miles across

and packs as much mass as 15.7 suns inside.

Up next are the intermediate-mass black holes,

it's nearly large enough to stretch from Florida to Maine,

black holes start to get pretty big compared to Earth,

when you consider the sheer mass they carry.

spanning a region about 172,000 miles wide,

but inside is as much mass as 47,000 suns.

which lives at the center of our Milky Way galaxy.

It covers a region about 14.6 million miles in diameter.

compared to other supermassive black holes.

Take the one at the center of our neighbor,

which has a diameter of 516 million miles,

to some of the largest black holes in the universe,

that surpasses the size of our solar system.

So let's look at the supermassive black hole

so it would stretch further than Uranus' orbit,

and it has about the same mass as 660 million suns.

And the supermassive black hole at the center of Messier 87

But this supermassive black hole, as large as it is,

So we have to look at one of the most massive

It has a diameter of about 78 billion miles.

For perspective, that's about 40% the size

of our solar system, according to some estimates.

about 21 billion times the mass of our sun.

black holes can be millions of times larger

than suns and planets or as small as a city.

It all depends on how much mass is inside.
