All language subtitles for 27 Facts That Will Make You Question Your Existence

This is Earth.

This is where you live.

And this is where you live in your
neighborhood, the solar system.

Here's the distance between the Earth
and the Moon.

Doesn't look too far, does it?

Think again. At their farthest point,
the Earth and the Moon are 252 ,088

away. Inside that distance, you could
fit every planet in our entire solar

system. But let's talk about planets.

The Great Red Spot on Jupiter, that's
about two times as big as Earth.

And Saturn is about nine times wider
than Earth.

Saturn's rings are so large that a few
of the fragments within them are as

as mountains.

But that's nothing compared to our sun.
Just remember, this is Earth.

And this is Earth from the moon.

This is Earth from Mars.

Here's Earth from just behind Saturn's
ring.

And here's Earth from just beyond
Neptune, 4 billion miles away.

But a billion's a big number, so let's
put that in perspective.

1 million seconds equals about 11 and a
half days, whereas 1 billion seconds

equals over 31 years.

Let's step back a bit.

Here's the size of Earth compared with
the size of our sun.

Terrifying, right?

And here's that exact same sun from the
surface of Mars.

As Carl Sagan once mused, The total
number of stars in the universe is

than all the grains of sand on all the
beaches of the planet Earth.

And there are some stars out there that
are much, much bigger than our little

wimpy sun.

The biggest star we know of, VY Canis
Majoris, is about 2 ,000 times the

diameter of our sun.

But none of those compares to the size
of a galaxy.

In fact, if you shrink the size of our
solar system down to the size of a

quarter and shrink the Milky Way galaxy
down using the same scale, the diameter

of the Milky Way will be roughly the
size of the United States.

That's because the Milky Way galaxy is
huge.

Its diameter is about 100 ,000 light
-years wide, which, when converted to

miles, is about 621 ,371 ,192

,237 ,333 ,890 miles.

Inside of all of that is you.

You live in this tiny, tiny portion of
the Milky Way.

But even still, our galaxy is a little
runt compared with some others.

NGC 6744, a spiral galaxy similar to our
own, is twice as wide as the Milky Way,

stretching over 200 ,000 light years
across.

It is massive.

But let's think bigger.

In this picture alone, taken by the
Hubble telescope, there are thousands

thousands of galaxies, each containing
millions or billions of stars, with

own planets.

Some of the objects seen here may have
formed as many as 11 billion years ago,

just 3 billion years after the Big Bang.

This period of time is considered one of
the busiest star -forming periods.

And just keep this in mind.

That's a picture of a very small, small
part of the universe.

So if you're ever feeling upset about
your favorite show being canceled, or

fact that they play Christmas music way
too early, just remember, this is your

home.
