[heroic music] ♪ ♪ - Sunspot?

What are you doing?

- Sunspot says he's going for a swim in the lake.

- [teeth chattering] - Uh, sorry, Sunspot.

It's winter on Earth now.

It's too cold to swim.

In fact, the lake is covered in ice.

No more summer ever again.

[sighs] I'll miss the sunshine, warm air, and flowers.

[sighs] But this snow stuff is pretty great.

- Wait.

What do you mean there's no more summer?

- Jet, winter won't last forever.

Summer will come in a few months.

- [gasps] It will?

- Sure, Jet.

Don't you remember about seasons?

- "See-suns"?

- Yeah, like, spring, summer, fall, and winter.

We learned about them in preschool.

- Jet, remember when Christmas came last year?

And we had to wear winter coats and hats to stay warm?

- Uh-huh?

- And then spring came.

And the snow melted, and we wore raincoats and boots and splashed in the puddles?

- Yeah.

- And then summer came again, and we didn't have to wear coats anymore because it was so warm?

- Uh-huh.

- And then in the fall, all the leaves fell off the trees?

- Yeah.

- Well, now it's winter again.

- Oh.

- But spring will come soon because that's how seasons work.

- Cool.

- They happen in a pattern every year.

- Oh.

Yeah.

I have no idea what you're talking about.

[wind whooshing] all: Whoa!

[sleigh bell music] - Oh, right!

I remember doing the Christmas pageant, when it was all snowy outside.

And I guess it did get warm again after that, because we swam in the lake.

Okay, but what causes these Earth "see-suns," anyway?

- Oh, I know.

Wait, no, I don't.

- Um, seasons happen because... because... [wind whooshing] - [gasps] Sunspot!

Where are you going?

- Oh, Carrot, what are we gonna do about this new assignment?

Our Bortron boss wants us to do an article about summer activities on Earth, but it's the middle of winter.

- And it's due tomorrow.

- If only we could find some summer somewhere.

- Ah-ah-achoo!

- Carrot.

Are you all right?

- I--I don't know.

[sniffs] I can't breathe through my nose, and I--I keep having these sudden face explosions.

- Oh, dear.

This is very alarming.

- Mr.

Propulsion, do you have a cold?

I heard you sneezing.

[together] A cold?

[laughter] - Uh, no, no, no, no.

I'm not cold.

I've been inside all day.

In fact, I'm feeling overheated at the moment.

- Silly.

A "cold" is when you're sick.

- I thought a "cold" meant the opposite of "hot."

- Well, that too, but a cold is also a name for a kind of sickness that Earthies sometimes get.

- And speaking of cold, Mom and Dad, did you know about this Earthie thing called "see-suns"?

It's when the weather goes from cold to hot and back again.

- Oh, well, of course, Jet, like winter and summer.

In fact, your father and I were just trying to figure out what to do about summer.

- What do you mean?

- We need to write a travel report about summer activities, but it's the middle of winter.

- Not everywhere.

- Wait, what do you mean?

- When it's winter here, it's summer somewhere else.

And when it's summer there, it's winter here.

- Oh, oh, what?

That's remarkable!

- Sure, sure, sure, that's great.

But do you know what causes seasons?

- Oh, uh... - Oh, well, uh... - You know what, Jet?

We're not really sure why seasons happen, just that they do.

- Maybe the Sun is bigger in the summer, so it's hotter, and smaller in the winter, so it's colder.

- Hmm, I never noticed the Sun change size in the sky.

Maybe it's summer when the Earth moves closer to the Sun and winter when it gets farther away.

- [chitters] - Oh, hang on!

Sean gave me this big book of space for my Earth-day birthday.

Maybe there's something in here about seasons.

Ah, here it is.

[clears throat] The book says that the Earth has an imaginary line that runs up and down the center of it, called an "axis."

The Earth spins on this axis like a top.

But the Earth's axis is tilted to the side, and this is why there are seasons.

all: Ohh.

- I don't get it.

- I don't think I do either.

Why would a tilted axis cause seasons?

- Hmm, do you suppose it has something to do with the Sun?

Hmm, why don't we do a demonstration, so we can understand it better?

We can "pretend" to be the tilted Earth and the Sun.

[all cheer] - Whoo-hoo!

- Yeah!

- Let's do it!

- [sneezes] [crash] - Carrot, my goodness!

So many face explosions!

First, we'll need to find something round to represent the Earth.

Perfect.

Now we need a little light to represent the Sun.

- Found one.

- Great.

Now, turn on the lantern, and let's turn off the lights.

[lantern clicks] - Hmm, it looks like Sunspot is lit up the same from top to bottom.

[all murmuring] - Yes.

Now, Sunspot, can you lean slightly to one side?

Like the Earth tipped on its axis?

- Sunspot's top half is getting more of the light.

So I guess, on Earth, that's where summer would be?

- That's right, Sydney.

Okay, now, Sunspot, if you'd please move to the other side of the Sun but make sure to keep tilted in the same direction.

Okay.

When the Earth travels around to the other side of the Sun, the bottom half gets more direct sunlight.

So it's summer there.

The top half doesn't receive as much direct light, so it's colder and therefore winter.

- So that's how summer and winter can happen at the same time?

- Oh, this is great news!

- [sniffs] It means that we can turn in our travel report after all.

We just have to go where it's summer.

- So let's go find some summer!

[all cheer] - Whoo-hoo!

Although, I guess there, they'd think it was just as weird for Christmas to happen in the wintertime.

As long as we're here, we might as well sit the saucer down and go for a swim.

[kids cheering] [gentle music] - And we even saw a palm tree decorated for Christmas and a surfing Santa Claus.
