if a black hole appeared in our Solar System.

that has been crammed into a very small space.

Being so compressed gives them an incredibly strong gravitational pull.

Not even light can escape a black hole's grasp.

And if you get too close to a black hole,

A black hole entering our Solar System would not be good news.

The extent of the havoc that a single black hole would wreak on the Solar System

and how far into the Solar System it got.

If we're talking a supermassive black hole,

like the one residing at the center of our Milky Way galaxy,

A monster that size would cause us trouble

even from a distance of a few light years away.

Presumably, supermassive black holes have stars, planets,

asteroids and comets orbiting around them.

All the debris that a supermassive black hole picked up on its way through space

Then, that gigantic black hole would tug whatever was left into an orbit around it.

wiped out by some rogue planet that smashed into Earth.

Let's try our chances with a stellar black hole.

This is a black hole that's up to 20 times more massive than our Sun.

If this kind of black hole made it to the outer reaches of the Solar System,

it would cause a gravitational mess in the Oort cloud -

A stellar black hole would hurl more comets and asteroids

As the black hole made its way through the Solar System,

it would disrupt the orbits of all the planets in it.

Likely, our space intruder would tangle the biggest planet in the system.

The black hole would pull all the gas from the giant planet,

It would keep pulling until it consumed Jupiter entirely.

What would happen to our own planet in this gravitational mess?

The black hole would start affecting us even from a distance of Pluto's orbit.

First, it would pull us out of the habitable zone,

and we humans might not be ready to adapt to this change.

We wouldn't have much time to complain though,

it would cause the cracking of the planet's crust.

We'd see extreme earthquakes and volcanic eruptions.

The ocean tides would be devastating, too.

By the time the black hole passed Earth's orbit,

there would be nothing left of our planet but a sterile surface paved with magma.

Maybe Earth would be ejected from the Solar System altogether.

because when the black hole got close enough to the Sun,

it would start drinking up the Sun's flaming gas,

and pulling our center of gravity into its insatiable stomach.

If somehow, Earth stuck around for the afterparty,

it would be torn to shreds and consumed by the black hole.

Luckily, black holes don't seem to be very numerous in the Universe.

The chances are better for a rogue planet to enter our Solar System.
