[Sunspot screaming] - [chuckles] I guess that means brain freeze.

- Man, it's as hot out as I can ever remember.

- When is it gonna be cold again?

- [sighs] Not until winter.

- When is that?

- You guys!

I just was watching skaters on TV.

They make me want to skate, like we did last winter.

- [laughs] Ah, right.

Remember when the lake water froze so hard, we could ice-skate on it?

Ha!

I love winter.

- Yeah, why does it have to be summer for so long?

[gasps] Hey, Jet, can you make it winter so we can skate?

You can make one of your inventions.

- What a great idea, Mindy!

- Whoa, whoa, guys.

You can't just change the seasons.

You have to wait for summer to end.

- And then for fall to come, and winter to come after that.

- So it'll take six months for winter to come to Boxwood Terrace.

- Six months?

That's, like, forever.

I sure wish we could ice-skate now.

- Huh.

So we have a problem.

I love problems!

Huh.

On Earth, to have ice to skate on, it needs to be cold, or the ice will melt into water.

- Right, and you can't skate on liquid water.

- And it's hot summer now, not winter.

But we do have a flying saucer.

Why don't we use it to bring winter to Mindy?

- Sure--wait, what?

- [gasps] Yay!

[both clapping] - Sean, there's lots of ice out there in the solar system, enough to make a teeny little winter in my yard, at least for the afternoon.

- [sighs] - I love this idea.

- I don't.

Jet, why can't we just get ice from the supermarket, or, I don't know, at least Antarctica?

- [gasps] - Bup bup bup bup!

I know, I know.

The next thing you're gonna say is, "Let's fly out to Saturn."

- Uh, no, I was gonna say, "Let's fly out to Antarctica," but Saturn is even better!

[laughs] Great idea, Sean.

- Wait, I didn't mean-- - Sean, the ice in Saturn's rings is cold, really cold, so Saturn's ice is the best!

It'll stay colder longer.

- What a perfect way to beat the heat on Earth-- fly to Saturn and collect some ice.

- Hey!

There's my house.

- And there's the Petersens!

[Sunspot barks] You're right, Sunspot.

That is the DSA.

- And here's where my first tooth fell out.

- Look how close my house is to Jet's, and how far Mindy's house is from the tree house.

- [squeaking] - Oh, I just love maps, especially this flat kind made of paper.

- Well, what other kinds of maps are there, Jet?

- The Bortronian kind!

Sunspot?

- [squeaks] [device whirs, chirps] [mystical music] - Whoa!

That's such a different map.

- It's a hologram map, Mindy.

- Bortronian technology.

Boo-yah!

Look how these inner planets are closer to each other, like Mars and Earth.

- And how these outer ones are farther apart, like Uranus and Neptune.

- You're right!

Some are really far apart, because the solar system is really, really, big.

- These maps are so cool.

Maybe we can make our own map of the neighborhood.

- Great idea!

And we could include stuff like Sunspot's pet house and the lawn chair!

- Or we could make a new map of the solar system.

- That's a great idea too!

We could include the Sun and the Moon and--and all eight planets!

- Or we could do something even bigger.

We could combine Mindy's idea and Sean's idea and make a map of our solar system right here in our neighborhood.

- [laughs] Whoo-hoo!

That sounds cool-some!

- Especially if we make it big enough to run around in.

- Ooh!

I love running around.

- [squeaks] - But, um, what exactly do you mean by a map of the solar system in our neighborhood?

- Hmm.

- Uh, let me explain.

Imagine all the familiar things in our neighborhood.

We can pretend those things are the different planets and the Sun and the Moon.

- Double whoo-hoo!

- We can make a small model of the solar system in Jet's backyard.

- And then use that model to make our own big we-can-walk-around-in-it map right on our street.

- Exactly!

Let's make a solar system model.

- Yes!

Ready!

Jet!

Go!

- This pineapple can be the Sun, this ball can be the Moon, and this ball can be Earth.

- Ooh, how 'bout this orange as Saturn?

- And let's pretend this apple is Jupiter.

- [squeaks] - [giggles] - This ball can be Venus, and these other objects can be the other planets.

- [squeaks] - Uh, guys?

This model doesn't look right to me.

- How come, Sean?

- Well, the scale and distance between the planets are wrong.

Mercury is too far from Venus.

Look at this picture in my book.

Hold on, it's a fold-out page.

- Whoa!

- Wow, this is a huge page, just to show the solar system.

- Well, that's 'cause the solar system is really big.

This map shows distances between the planets more like they really are.

Look, we put Neptune too close to Uranus.

- No problem!

We'll just move some stuff around.

Um... Whoa--uh... [chuckles] There you go.

- Good try, Jet, but now Mars is too close to Jupiter.

- Don't worry... - [squeaks] - I can fix it.

[grunting] There.

- Uh...well, that didn't help either.

Now the Moon is too far from Earth.

- [squeaking] - Boy, making this model is harder than I thought it would be.

- I guess figuring out how far apart things are in outer space is different than figuring out how far apart things are in our yard or on our street.

- We should try to figure out exactly how scientists measure things in space.

- Measure?

What's that?

- Oh, oh, I know this one!

A measure is a big wooden box filled with coins and jewels that you bury in the sand.

- [squeaks] - Uh, no, Jet.

That's treasure.

For making our model, "measure" means figuring out how far apart things are, like when you use a ruler.

- Oh, yeah.

[chuckles] Got it.

- So scientists have giant rulers that they use in space?

- If they do, they'd have to stretch out really far, like Sunspot's tongue.

Show 'em, Sunspot.

- [squeaks] - Wow, Sunspot's tongue is long, but it still wouldn't be long enough to measure things in space.

[tongue rattles] - [squeaks happily] - So how do scientists do it, then?

- Let's find out.

- Whoa, get this.

Things in outer space are so far apart that scientists came up with a brand new way to measure things there.

It's called an astronomical unit, which is the distance from the Earth to the Sun.

- Wow!

A way to measure things just for outer space?

- That is the coolest thing I've heard since, well, Sunspot played my flugelhorn.

- [squeaks] [horn music playing] - Man, Sunspot, that is cool.

- So back to Earth.

Let's see.

The distance from the Earth to the Sun is one astronomical unit.

- Look, this is how long one of those astro-whatcha-ma-call-it thingies is.

- Uh, astronomical units.

- Now let's measure how far it is from the Sun all the way to Neptune.

- [laughs] 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13... - [squeaking] - 14... [video fast-forwards] 30!

Whoa.

That means it's 30 astronomical units away.

- That's really far.

- Yup, because outer space is very, very, very big.

- Okay, so now that we know about how scientists measure distances in space, how can we measure things for our big neighborhood model of the solar system?

- Hey, I know what to do, and we don't need a ruler or Sunspot's tongue.

Look, I can walk 15 steps from Jet's garage to this table, and I would know it's 15 steps away.

- You're right!

Steps are a great way to measure.

- That's it!

We can use steps to figure out how far away the planets in our model of the solar system should be.

One, two, ta-da!

- Hm, well, the problem is that not all of our steps are the same size, so maybe we should do what the scientists did.

- Which is?

- Come up with our own unit of measure.

Not steps or an astronomical unit, but... - [squeaking] - Sunspot!

Sunspot can be how we measure things, because he's always the same size.

[all laugh] - I love it!

And I love Sunspot.

- Wait, I don't get it.

- See?

In our map, one Sunspot will equal one astronomical unit.

- Ah, now I get it.

- So what do you think, Sunspot?

Do you want to be our unit of measure?

- [squeaking happily] [cheers and applause] - What's he saying, Jet?

- Uh, well, that he's both excited and honored to be Earth's newest scientific unit of measure... - [squeaking] - And he is ready to help us make a solar system map in the neighborhood.

- [squeaks] - Then what are we waiting for?

all: Excelsior!

Okay, Jet 2, you're gonna be the Sun.

Now, stay right here, okay?

- Hello.

Sun.

Yes.

Measure.

- Great.

Now it's time to measure using Sunspot as our astronomical unit.

- Ready, Sunspot?

- [squeaking] - Okay then.

Let's measure.

[playful music] - First, we need to put Earth where it belongs, which is exactly one Sunspot away from the Sun.

- And what better thing to use for our Earth than this Earth soccer ball?

- Cool-some!

Now, let's make the rest of our walk-around solar system.

- This golf ball is Mercury, and it's not even one Sunspot away from Jet 2-- uh, I mean the Sun.

- Let's pretend this soccer ball is Venus.

It goes most of a Sunspot away from the Sun.

- According to the map, Mars is 1 1/2 Sunspots from the Sun.

And while it's a little big, let's use this pink lawn flamingo for Mars.

[laughter] - Okay, my turn!

Jupiter is five Sunspots away from the Sun.

Hey, look, Sunspot's pet house can be Jupiter.

- Okay, Saturn's next.

5, 6, 7, 8, 9, 9 1/2... - [squeaks] - Saturn is 9 1/2 Sunspots away from the Sun.

- [squeaking] - And Saturn is me... hula-hooping.

Whee!

[giggles] [Cody snoring] [both laugh] - Um, what are you guys doing with Cody?

- [whispers] He's gonna be Uranus.

[slow music] - Which is about 19 Sunspots from the Sun.

- [laughs] - Then there's only one planet left.

Neptune!

- Hey, guys, look over here.

The trampoline is Neptune, and it's 30 Sunspots away from the Sun.

- Then that can only mean one thing.

- [laughs] Our walk-around map of the solar system is now complete!

[all cheering] - Way to go, guys.

We had an idea, figured out how to do it, and did it all by ourselves.

- Well, we had a little help.

How about a special Bortronian cheer for our new unit of measure?
