The planet of One Piece

[lpzie]

Not sure if anyone's noticed/mentioned this, but this has been something I've always had somewhere in my head to think upon from time to time.

The planet of OP…

Does this answer questions… or question answers? For example, how is there a Never Night Island? Have we ever seen more then 1 moon in the night sky? Which moon did Enel go to? There should be a lot of unpredictable light/dark times during a normal 24 hour 'day' due to the projectiles blocking the light. Maybe another reason why it's hard to get an accurate timeline? Since night time might not even be the evening, but the morning. Could this answer some of the craaaaazzzy weather? How do the tides work with more then 1 gravitational pull? Could this explain how the Aqua Laguna completely dries up the ocean (all of the moons to one side of the planet.. a rare occurance)? If so, this should be something common at other places too.

By the looks of it, there's 2 moons on 1 path (maybe debris from something in the past?) and another 2 on another path. What are their speeds? Do they ever bump into each other. Whats up with that lopsided one? Does Oda have something in mind with this, or it won't even matter?

Discuss...

You bring up an interesting point. I never thought about the globe at the Tree of Knowledge…The planet at the center is very likely the OP world, since you can see the Red Line circling at least the part of the globe that is visible. About the other moons orbiting the globe, it is possible that the OP world still believes in a mostly geocentric model, and the other moons are actually planets in their solar system.

[Zephos]

Dude, we saw a globe in Volume 3.

[lpzie]

Did we? Can you post a pic? I must of missed it, or something =O

But I've never seen a globe model of Earth (classroom size, you know what I'm talking about… elementary/middle school) with the moon.

[Virgilijus]

They don't have to be moons; they could be planets that were put close to take up less room (every planetarium I've been to does that). Though it doesn't solve why there would be a place of all sun…maybe it's at the top of the pole of rotation; kind of like how Alaska gets 6 months of sun but to a greater degree.

[Augury]

@Zephos:

Dude, we saw a globe in Volume 3.

The "globe" shown in Volume 3 is a pictorial representation used by Nami when she is explaining the Red Line and Grand Line geography to Luffy and Gaimon. It doesn't include orbits of moons and such that are included in the globe at Ohara. Chapter 22, page 15, panel 1:

[Razza]

Looking at that more closely, is it me or are there planets orbiting the red line and the grand line?

[Ubiq]

Hmmm… I'm pretty sure at least one of those smaller globes is a planet because it has a moon attached to it.

@Razza:

At first glance, it does look like the planets are following those lines, but if you look closely enough, they're actually crossing the Grand Line and Red Line at an angle.

[LoudMouse]

that center globe doesnt necessary have to be the OP world….. it could be one of those small planets orbiting around it..... for example that smallest one with its own little moon (on the pic that one most far right) that biggest globe could be smthng like sun.....
Dont forget that this is manga where people can turn into girafes.... so anything is possible

That would be true if the center was the sun but you can clearly see continents on the globe. Also, you normally make the subject of interest ( the OP world) the biggest since you want to read/study this. The balls orbiting around it could be moons, sattelites, hunk-a-junk, rocks, meteors or even an ancient weapon! You never know with Oda :P

[Monkey Spirit]

And if you compare Nami's globe with it, you can see the same continents, only the Ohara globe is upside down.

I thought they might be the Ancient Weapons, too. Seeing how they're named after gods/planets…

Great find, Ipzie!

@Ubiq:

i think a moon can have its own moon, but i'm not too sure about this. i just can't see any reason why it wouldn't be possible.

[Porter]

@LoudMouse:

To me it appears to be the OP world and nothing else.
On the first look you see the Redline, circling the globe (as far as we can tell)…
Then, if you take a closer look, you can see a dotted line (running perpendicularly to the Redline) which apparently represents the Grandline.

Until now i thougt the north- and south poles would be located on top and bottom of the Redline, and the Grandline would circle the world like the equator.
But here (and actually even on the pic in vol. 3 ^^") you can see the rotation axis of the planet going thru (as the names already state) North- and Southblue.

So I'm pretty sure, that it represents the OP world.

The fact, that we never saw more than one moon, might be caused by the size and distance of the moons, or they are just to dark colored...
So that there is only one moon left that has the right size, distance and color to be seen from the planet...

[Voodzik]

@igalsfy:

I don't think moons can have thier own moons….Pluto and it's moon are the same size and kind of orbit each other, that's the closest I can think of.

That said, I wonder if there is something on the OP moon. Maybe that's what's on Raftel...the way to the moon.

[Porter]

The german wikipedia site says, there is no know case of a natural satellite (moon) having a natural satellite of its own.

But I think it should be possible, shouldn't it?
Isn't it just a matter of mass and distance?

Pluto is an other special case… some even lable it as double planet. ^^

I knew about the double planet thing.

And not really. An orbiting moon is in a very careful gravitational balance. Adding an element moving vontrary to that balance would flip the whole thing up.

[COWMAKAZE]

On the orbiting moon thing: I can see why it isn't possible. The gravitational pull from the planet would be far greater than that of the moon, correct? So, most likely, the moon's moon would just end up flying around the planet as a second moon.

On another note, anyone else reminded of the fact people a long time ago thought that the sun and all the planets revolved around the Earth, and not vice-versa? Just because this globe is in Ohara doesn't mean it is correct. But, then again, this is One Piece world, where eating a pear can make you Superman and people can rebuild themselves from scrap metal, so it's always a possibility that that's true.

Yes, this is the geocentric model of the universe I mentioned in my earlier post. Previously, I said "mostly" geocentric because in that picture there is a moon orbiting another planet which doesn't fit with the geocentric model where everything orbits around the Earth.

I apologize. I'm a bit sick at the moment so everything's in a bit of a haze. I must have pulled one of those moments when you think you're reading something, but you aren't really paying attention. I'm very sorry. Well, anyway, you bring up an interesting point. And, looking closer, do they even show a sun on that thing? I don't see any. Very strange.

[unchipu]

There was no need to for an apology. I wasn't offended at all, just restating what I said earlier. It's impossible to convey emotions over the net…
You're right that it's strange there's no sun there. The sun and moon(s?) would be the most prominent things in the sky, and one would assume these would be the first objects placed in any model solar system.

Unless the density per volume was very high, which could cancel out the bigger objects gravitational pull, and have a satellite of it's own… but it's a very very complex equation when you throw something like that into the mix. could be artifically made, or whatnot. i wonder how advanced the people were back during the lost history; to the point of doing work interstellarly?

Or maybe it's just a geocentric model after all.

[Bounty1Berry]

A moon could have a satellite of its own– just look at the fact we've parked small man-made satellites around our moon and Titan.

[Paulie]

Saying a moon can't have a satellite because the Earth is bigger than the moon is like saying the EARTH can't have a satellite (like, you know, our moon) because we orbit something larger; AKA the sun. Right?

[ybmc]

But if something were to orbit it, it would be simply because that's the biggest thing near it. If it were to orbit the moon, It would probably end up just orbiting the Earth instead, being bigger and almost as close.

[Porter]

@Bounty1Berry:

Ah, very good, that proofs it works just fine.

@Paulie:

Exactly. A planet is a natural satellite of the sun, and it has a natural satellite (moon) of it's own. So, there is no reason, why a moon shouldn't have a natural satellite, and so on.

@ybmc:

But if something were to orbit it, it would be simply because that's the biggest thing near it. If it were to orbit the moon, It would probably end up just orbiting the Earth instead, being bigger and almost as close.

Yeah, thats the point.
It has to be smaller (less mass) than the moon itself and be clother to it than it is to the planet.

[COWMAKAZE]

@Paulie:

That's a very good point. In no way do I know what I'm talking about, so don't mind me. I was just saying what made sense. But, in the world of physics, nothing really makes much sense at first.

[Voodzik]

@Paulie:

Saying a moon can't have a satellite because the Earth is bigger than the moon is like saying the EARTH can't have a satellite (like, you know, our moon) because we orbit something larger; AKA the sun. Right?

Wrong, because we're a ways different. And I don't think we've got any long-term satellites orbiting the moon; lots of stuff orbits earth and takes pictures of the moon as it passes by. And we have orbited the moon, but only with controlled rocket burns, where we were in control of our velocity and direction.

Well, chances are, Oda will wrap that into something cool sometime in the future.

[fy3]

now, which moon do u suppose eneru is headed to ? XD

seriously, after reading (actually, glancing) this thread, i've come to believe that rafteru might be a gateway to one of the moons which may be where one piece is located

but thats not the only theory

i've also considered the possibility of an island within the grand line that has a direct link to one (or all) of the moons

there's also the possibility of the old kingdom (empire)'s citizen's having a mass exodus to the moons

how abt the possibility of devil fruits being originated from the moons?

but after careful thought, i've concluded that i've been thinking too much and has yet again gone off topic
sry sry

but i have a question though
archeologists are supposed to deal with historical matters right?
they're like the csi of history.
and astronomers are supposed to deal with blinking dots in the skies right?
do you suppose that the very presence of the globe and the moons in the archielogists's place is part of oda's foreshadowing to some of the theories i've stated above?
i mean, its okay for them to have maps and a globe, but why include the moons?

[Ulrilra]

Since when has Oda known anything about astronomy? Or any type of science for that matter? He's good at drawing, story-telling, and imagination - that's it. Everyone knows he dropped out of college…

[Raoul]

Man, he can always do some research for the sake of his manga you know.

[Voodzik]

@Raoul:

Yes, yes he could, but would he bother? he thinks giraffes are a kind of cow…

A good point has been brought up. We should not assume that the physical impossibility of moons having moons has prevented Oda from doing it. Hmm...odd moons could be what causes Aqua Laguna.

You can have a long term satelite around the moon; the sun analogy is pretty much right. Depending on how far the moon is away from the planet and the mass of the moon, it could easily have a moon of itself as long as the mass of the larger moon over the distance from the larger moon to the smaller moon squared is greater than the mass of the planet over the distance from the planet to the smaller moon squared. :happy:

kekeke…. A Giraffe is very closely related to a cow, so they go into the same category, like wolves, dogs, and jackals are all in the same type of Zoan, just a different model. Knowing Oda, he probably has 3 times more Zoan in store, considering how much he loves animals (and because we've seen only one model of the tori tori no mi, he's got at least one more of them in store.)

[Voodzik]

Wolves, jackals, and dogs are in fact all Canines. Giraffes are like, Giraffaria or something like that, their only surviving realative being the Okapi. Cows, on the other hand, are Bovines. So you see wolves, dogsd and jackals are in fact all dogs of one kind or another while Giraffes are a completely different kind of thing.

[Virgilijus]

Giraffes share the same order with cows, so they are pretty closely related. The okapi is probably the only one more closely related to the giraffe than the cow (horses only share the same class). So Oda wasn't far off, maybe he stretched it a little, but hey, he can take those liberties.

[Ziggy]

Giraffes: genus Giraffa-family giraffidea (including Giraffes and Okapi)
Bovidea is a seperate family but hey, for all Oda cares Giraffes can be related to duuuuucks and daaaaaachsunds (on the island where everything was streched out.)

[Kuzan]

Allow me to explain the confusion.

Giraffes and Cows are from the same order, they are Artiodactyla (even-toed ungulates).

It happens that artiodactyls group, is commonly known as "Cow family" and have three orders:

Suiformes: with the families suidae (pigs, hogs), hippopotamidae, etc
Tylopoda: with the family camelidae (camels, llamas, alpacas…)
Ruminantia: with many families which include giraffidae and bovidae (goats, sheep, cows)

The confusion is that they are not in the same biological family, but the order they are in (Artiodactyls) is familiarly and sometimes called "The cow family", although not referring to a biological family in a strict sense. So oda isn't wrong saying they are from the cow family though it would be wrong to say that they are from the same biological family. Plus, you'll have to agree that "cow family" works better than "ruminantia suborder" for a manga.

Also don't forget that these classifications could be different in the odaverse as long as they don't break any scientific precept. IMHO, there's no error here.

[Master O]

Well, that was a long explanation about the Giraffe related to the Cow…

Good work!

[Voodzik]

@Master:

Well, that was a long explanation about the Giraffe related to the Cow…

Good work!

I still say it's a bit of a stretch. Then again "Giraffe Giraffe" fruit is a mouthful.

So we've either proven that Oda does no research at all or a whole freaking shitload, so he could have researched the planet of one piece (the topic, remember)

[Ziggy]

I dunno, it looks like with so many moons having their orbits so close to each other they would crash and bring a fiery death to everyone on earth. I don't really think that model is possible…although it is fun to look at.
And is it just me or does one of those moons look like a devil fruit, eh, I guess it's just me...

[Throes]

Well, remember, it's probably not an accurate model either. Some moons could be farther from the OP world than others. And who's to say that a moon can't have a satellite of it's own? Look at the sun, now consider that as a planet, it has satellites, and several of it's satellites have satellites of their own! Oda showing us the OP planet this way clearly means something, because most things he throws in never dead-end into nowhere. (too bad the same can't be said with the recent "War of the Worlds" movie)

[ITSALION]

Wow, paying accolades to the Oda while simultaneously dissing War of the Worlds! Omg. You get bonus points.
–-ON TOPIC---
Who the hell cares? These moons can do whatever the F*CK they want. This is friggin' One Piece. We have a guy who turns into cigarette smoke. Maybe the moons were just stuff he put on there to make it look cool.
Or maybe not. Perhaps the reason Mariezoa is called the holy land has something to do with the intersecting axes of the moons.
BTW, the moon Eneru went to was the crater-y one in the top left corner of the picture.

[DarkShinobi]

The Strawhats going to the moon when reaching Raftel…..Reminds me of the infamous "One Piece in Space" topic a few months back.

As for working the moons into the overall storyline, that's a very probable idea. I'm sure Oda will find SOME special use for them.

Except the sun ISn't a planet. You're talking about a level of gracitational forces on a completely different scale.

[unchipu]

This is true. If you're thinking about the sun and planets and moons, let's take the Jupiter system as an example (Jupiter has multiple moons unlike Earth). Jupiter is about 1000 times less massive than the sun. The largest Jovian moon is around 10,000 times less massive than Jupiter. So then, the moon is 10,000,000 times less massive than the sun.

For a planet like Earth and our moon, the moon is about 100 times less massive than the Earth. Even if we took off a factor of 10 for the mass of a hypothetical moon's moon, and said it should be around 1000 times less than the moon, we would get something the size of a large asteroid (around 400 km in diameter, ~10% the diameter of the moon).
That being said, it is still very unlikely of having a multiple moon system where the moons are comparable in size and mass to the host planet, because the system is unstable. It is impossible to predict the movements of a three or more body system. The Jupiter/Solar systems work because the parent body is significantly more massive than the satellites, and the satellites don't feel the effect of the others.

Of course, we need to keep in mind this is the Odaverse, and regular physics need not apply.
