Take a Trip Through Space!
Hello, I’m Hank and I talk about how things
work for my job. When I do this, I use a lot of big words . Sometimes I have to, but other
times I think maybe we only do that to sound like we know lots of things. Randall Munroe of XKCD has written a whole
book explaining how things work using only the ten hundred most used words. I really
like that book, and so we thought maybe we could do the same thing. So here is a look at our star area, using
only the ten hundred most used words in our language. Our world is big and great, but it is only
one of a lot of worlds that go around the sun. The sun is a star, like all of the other
stars you see at night, but much closer up. The sun is the biggest thing near us. Next
to the sun, our world looks tiny. We are close to the sun, but not the closest.
Closest is a small but heavy world. The sun’s power pushed all of the not heavy stuff away
from this world, so only the heavy stuff remained. The side that is facing the sun is always
very hot, but because there is very little air the dark side cools off very fast at night. Second is the hot sky world. It’s a lot like
our world but it’s very hot. One reason it’s hot is because it’s closer to the sun. But
it is also hot because it has a really thick sky that warms it like it’s wearing lots of
shirts. This world is so hot that if you landed there you would be on fire. It can be even
hotter than the heavy rock world. Next is our world, which you know all about.
Our world has a moon, which are worlds that go around other worlds that go around a star.
Our moon was probably made when a world slammed into our world a very long time ago. Even further out is the Red World. The red
world is my second favorite after our world because it had water like our world when it
was very young. It is cold and dry now, and all of the water is ice. But because it once
had water, we think maybe it could have once had life on it. Next we have a large area of small worlds
that some might just call big rocks. Only one or two of these worlds are big enough
to even be round, we just sent a space boat to one for the first time, which was exciting. After that are the Big Worlds. This is where
most of the air went when the sun pushed all the light stuff out of the inside of our star
area. These big worlds are made of almost all air. The first one is the biggest world,
which has a storm so big that our whole world could fit in it. The big world has lots of
amazing moons like the ice water moon which is warm on the inside, and so things might
be able to live there. The Ring World is the next air world, it’s
a lot of people’s favorite world because it’s so pretty. It also has an ice moon, and a
lot of other really cool moons. The rings are very bright, even if they aren’t very
thick. There are two more air worlds, they are smaller
and have more kinds of air, including the kind of air that we pull out of the ground
here to warm our houses. That kind of air makes them more blue. The closer of these
worlds rolls on its side around the sun instead of spinning like all of the other worlds.
We don’t really know why, but we think maybe some other worlds hit it when it was young
and turned it to its side. After the air worlds are the cold dark worlds.
These are small, but many and made of ice and rock. We just sent our first space boat
to one of these, and it was pretty much the best day this year. The pictures are very
good. Worlds like these go around the sun very slowly in a big wide ring. Even farther out there are a lot of small
ice worlds that sometimes get pushed into our area and, as they get close to the sun
the ice burns off which we can see in the sky. We also just sent our first space boat
to one of those, which is another reason why this year was great. The final reason this year is great is that,
as of today, this book, “Thing Explainer” is a thing you can buy at all of the places
where you would think to buy books. Thank you to the book making people for paying us
to make this. And thank you for watching this moving picture
thing, we hope you watch more of them soon!
