A/N: I tried to look up the distance from Suna to Konoha on google… and it was pathetic (someone said their lowball estimate was over 70,000 kilometers). This is a detailed study that justifies my decisions and such in "Hinata Supreme" (e.g. Free Running on native terrain is about 40 km/h, sprinting is faster and Body Flicker faster still) and all other Naruto fics I might write.

"The new sciences have given us a number of different ways to describe and measure the world around us. Let us send these learned men out into the world in general and into our country in particular. We cannot know what resources are at our disposal until we have thoroughly searched all our lands for minerals, counted every last subject and assessed every last enterprise." –Europa Universalis IV, Admin Tech 23, "Measuring the World"-


Chapter 1: Lift Your Hands to the Sky

The fight is done, the war is won,
raise your hands toward the sun…

Star systems… the basic unit of galactic civilization… tend to be rather predictable affairs. The Naruto World is no exception.


On October 10, the Nine-Tails attacked Konoha.

Twelve-year-olds are not considered physically mature enough to be breeding, and are of similar physical size and maturity to Earth 12-year-olds. We assume that Naruto World humans develop comparably to Earth humans.

These two facts immediately tell us several things. First of all, the calendar of the planet is at least very similar to the Earth calendar, as seen by the organisms' development cycles and the fact that they have, apparently, a 12-month year.

To claim then that the planet itself is similar to Earth (complete with a large moon) is too far for now. So let's hold off on that for now.


The star the Naruto World orbits is a yellow to white star. This means that the habitable zone for Earth-standard life (which the Naruto World has) is comparable to that around Sol. Within this habitable zone, the planet will have an orbital period most likely between 300 and 400 Earth days. It also has a large moon.

Less euphemistically, it is an Earth analogue in terms of year length, general climate, etc.

Now let's move on to the size of the planet, its galactic locale, and the feasibility of certain planet sizes.

We automatically eliminate ludicrous claims such as Ei (because Word spell-check HATES a single capital A for grammar, at least adding that to dictionary makes it shut up) taking 60 seconds at light speed to reach Madara. The Sun is about 4.65 light-seconds across, so the Naruto World would need to be nearly flat (because the Elemental Nations map is flat and we don't see any globes in the series that I'm aware of, so they haven't figured out that the numbers for distances just don't add up to a flat world) across a length 12 times the diameter of the Sun. That is so large and massive that at terrestrial densities, it would probably collapse into a neutron star or even, thereafter, a black hole.

The fact that the Nine-Tails attack on Konoha scene in the anime has no stars visible due to the burning village shows us that the Naruto World is not within a galactic core region, or stars should be visible still due to the density of white-blue sub-giant to blue supergiants in the area. By the way, due to frequent supernovae galactic cores are not conducive to development of Earth-like planets due to atmospheric stripping and irradiation of surface life that made a breathable atmosphere by frequent supernovae. Thus the planet would have had to be terraformed by back-to-nature nuts from an advanced human civilization if it was in a galactic core region.

By stellar development, yellow, yellow-white or white stars should not have enough dust in the inner system to form a mostly rocky planet much larger than about three or four Earth diameters at absolute max. There is no particular reason to believe this is the case either, given the architecture we see is stuff that would work on Earth, instead of having to stand up to three times the gravity.

If the Naruto World was as large as assuming ninja can do Free Running in their native terrain at anything above something like 40 km/h, the distance from Suna to Konoha, coverable in 60 hours with minimal rest, would make the planet large enough (to avoid realizing distances didn't match up to a flat world) that it would have kept a thicker atmosphere. That way, with its orbital period and associated distance, it would easily have been a Venus-like Hell World, or been big enough to have attracted enough gas early in stellar formation to be a hot, close gas giant.

Therefore, the Naruto world should be an Earth analogue, and the Elemental Nations are, at absolute most, spanning a continent around the size of Europe, from Iberia and Iceland to Scandinavia and Anatolia. This is AT MOST, just based on climate, star colour, etc. for a very simple, quick analysis!

Details on further size restrictions (which usually make things smaller) will come in the next chapter of this dissection of how utterly insane most of the distance estimates for the Naruto World are.

Anyone who complains that while Naruto obviously has a somewhat industrialized world from food packaging and such but lack cars because Ninja abilities replace them should remember just how goddamned slow early cars and trains were (much slower than people, or at least horses, can sprint). Evolution of culture and technology also doesn't move from one fitness "peak" to another… in other words the Ninja world cornered itself into a dead end by relying on chakra too much.


A/N: Because anyone too stupid to realize ninja could not yell at each other effectively if they were moving more than a few dozen meters per second through the air that conducts their chatter needs to read this.
