Coruscant Population
Who said that Coruscant's Population is 1 quadrillion? The figure cited over and over in the star wars universe is 1 trillion. That's kinda a difference from a quadrillion. A factor of 1000 actually. I will revert to a Trillion until someone cites evidence that shows otherwise (and no... back-of-the-napkin calculations based on guesstimates for population density/surface area don't count).

Y'know, if Coruscant were the size of Earth, the population density would be 5076 people per square mile, which would practically make Coruscant a planet of rowhouses - unless a good portion of the people on Coruscant were fabulously wealthy and had whole chunks of skyscrapers to themselves. Of course, Coruscant might actually be a smaller world with an atmosphere that bends the light slightly. Hard to tell from Star Wars' density. But you said guesstimates like the above don't count, so why bother you? - Rickyrab To further back myself up, I have posted this clip from the Ep I Worlds book to cease all arguments. Star Wars canon states that these books are G-canon and outrule any contradiction. -- Riffsyphon1024 03:14, Apr 7, 2005 (UTC)
 * The population density of the poor regions near the bottom of the planet which be much, much higher than the density of areas near the top, in which wealthier people would own more land. Just like the population density of the most populated areas of Africa are higher than the population densities of the most urbanized areas in North America or Europe. bob rulz 08:58, Jan 9, 2005 (UTC)
 * Not all areas of the planet would be inhabited by the same population density. The Works takes up alot of room yet it is a manufacturing district that was abandoned. In other districts, however, say the financial, senatorial, or entertainment districts, the density could easily be over a million beings in a square mile, because the skyscrapers in those areas are more than a mile high each. Riffsyphon1024 02:22, 14 Jan 2005 (UTC)
 * Actually, older reference books claim 176 billion, which is almost as absurd as Trantor. Another case of canon conflicting with logic... SpaceCaptain 23:59, 25 Mar 2005 (UTC)
 * I will check the Inside the Worlds of... Episode II reference book to find the figure because that source will be G-canon. See also: Star Wars canon. -- Riffsyphon1024 16:05, Apr 6, 2005 (UTC)
 * Okay, if you can find the figure, put it in the table at the top, but can you leave in the section on the dispute? It is, after all, disputed frequently. SpaceCaptain 23:36, 6 Apr 2005 (UTC)
 * I could not find the section I was looking for in the Ep II, but it is in the Episode I Inside the Worlds book, stated at 1 trillion. -- Riffsyphon1024 02:33, Apr 7, 2005 (UTC)
 * No, those books are NOT G-Canon. Actually read the article on Star Wars canon: only the movies, scripts to those movies, the novelizations of the movies, radio dramas of the movies, and direct statements from George Lucas himself is G-Canon, everything else is at most C-Canon.  This has been explicitly clarified on starwars.com (http://forums.starwars.com/thread.jspa?threadID=194183&tstart=75) among other places, the misunderstanding began when the author of one of those books said that his books were "canon", which was mistaken by fans to mean "G-canon", when he spoke imprecisely.  --Wingsandsword 06:25, 3 September 2005 (UTC)

The population of Coruscant is 1 trillion. The statistic of 1 quadrillion is a fan estimate. -- Heddfones 22:08, 23 July 2005 (UTC)

Using the population density of Honk Kong (which includes industrial areas) and the surface area of earth you get a population in the area of 6 trillion, and thats without the massive increase in population density that having such taller buildings would allow.

With fictional works there is no point in doing internal estimating and fixing the population based on that. Some peoples ideas about the current distribution of world population might not pass munster. However the point is that this is an encyclopedia, and we are just reporting what other people have come up with in their fictionalizations.Johnpacklambert 00:33, 27 July 2007 (UTC)

Look, I know that Star Wars is Space Opera, not Science Fiction, so it's really fast-and-loose with the numbers. I'm cool with that. But the planet Koros/Empress Teta is 15,700km in diameter, has one city Cinnagar covering half of the planet's surface, and has a population of 1.3 billion. Earth is 12,740km in diameter, has innumerable cities that cover nowhere near half the planet's surface (take a plane trip sometime, or check the population density map about halfway down at Wiki: World Population for a quick overview), and has a population of around 7 billion (ibid).

Has the planet been recently and violently depopulated or something? It was around the 1870's when the earth had that low of a population. The only argument for Koros/Empress Teta having such a sparsely populated city over half its surface is that Coruscant (12,240km) has a population of 1 trillion (1,000 billion). The note about "additional transients" can't be referring to several trillion more people.

I can understand just picking numbers that seem "big," but c'mon, it only takes a few minutes to realize you'd need to seriously outstrip the earth's population in order to warrant a planet-city. Texas is 268,820 square miles in area, which translates to 7,494,271,488,000. Right away you can see that's roughly 1,000 square feet per person if everyone on earth were crammed into Texas. (Assuming 7 billion people, the estimate for 2013, the math comes out to 1070.6 square feet per person, for the curious.) If the city is 2 stories, that's 2,000 square feet to support each person. By comparison, Tokyo has 12.79 million people, with 1840.6 square feet devoted to each person... and while it is an impressive city, Cinnagar seems to dwarf the skyscrapers of Tokyo. For that matter, Coruscant's numbers are equally preposterous: The entire 1 trillion people of Coruscant could fit in the landmass of Eurasia with 581 square feet for every man, woman, child, infant... This sounds small, until you realize that Eurasia only covers 10.6% of the earth's surface. In fact, a little math... surface area of a sphere is 4*pi*(radius squared)... Coruscant's radius is 6120km, leading to... roughly 470,665,872 square kilometres of surface area, or 5,066,205,282,410,565 square feet. Divide that by 1 trillion and you get 5066 square feet, but let's be very generous and assume 1.5 trillion "additional transients" for a total of 2.5 trillion (2,500,000,000,000)... you get 2026 square feet for every single individual. Londons people have 2309 square feet to themselves, New York City's people get about half as much (1027 feet) space in the most crowded city in the US, and even the most packed city on earth, Dhaka in Bangladesh, manages 246 square feet per person. In any case, 2000-5000 square feet per person is hardly a city of the sort we see in canonical Coruscant. That's St. Louis, MO, that's Berlin... cities, yes, but nothing like what we see in Coruscant.

By traditional measures of population density (people per square kilometre), Coruscant ranks at 2,125/square kilometre (km²). Washington, DC, ranks in at 3,621/km², Dhaka is 43,797.3/km², Mumbai, the most densely populated city (in its metro area) on the planet is 21,880 /km², ten times as dense as Coruscant--without the nigh-stratospheric skyscrapers of 'Scant. Tokyo: 5,796 /km² London: 4,761/km² New York: 10,482/km² St Louis: 2,207.1/km² Berlin: 3,831 /km²

Empress Teta's city Cinnagar, which spans half the planet? 3.35 people per square kilometre, which is the equivalent to such wondrous, thickly populated sweathouses as Libya, Canada, Guyana, Iceland, North and South Dakota... Russia? Positively packed by comparison, the entire nation averaging out to 8.4/km². USA? Not even close: 31/km², ten times as dense, and Japan is an "insane" 339/km² (something like 75% of Japan is forested, though, so that's a bit misleading).

For the density of Dhaka, an RL city and among the densest populated (UN says Mumbai's more dense, but Wiki's numbers for both disagree with that), Cinnagar would need a population of 20 trillion (canon: 1.3 bil) and Coruscant would need... 23.5 trillion. And I don't suppose structures in Dhaka have 1000 stories to them as indicated by this image on Coruscant's main page.

That's a little too in-depth for Space Opera, maybe, but it didn't take that for me to know the numbers don't work. As soon as you note Koros/Teta is roughly earth-sized, has a city over half of its surface, and yet doesn't even have a population to match earth's in 1900AD much less its current population... yeah. WTFBBQ. Thoughts? --Sctn2labor (talk) 04:18, 18 October 2008 (UTC)

The 1 trillion is ambiguitous, because it can mean 10^12 or 10^18. Also, the sources say differenet numbers between 176*10^9 and 6.5*10^18, depending also if you interpret the numbers as long scale or short scale. --MrBurns (talk) 00:19, 1 March 2009 (UTC)

Surface water
Somebody chaged the value from <5% to 29%. Where does that figure come from? SpaceCaptain 15:39, 10 Apr 2005 (UTC)

Oh, sorry. I just see it in the picture. But I always thought it had very little. SpaceCaptain 15:40, 10 Apr 2005 (UTC)

Age of the city?
I didn't think the planetwide city predated the Old Republic; I thought ground was visible in Sith War era stories. SpaceCaptain 23:00, 13 Apr 2005 (UTC)

Source of O2
Surely a totally urbainsed planet would be uninhabitable? Where does the oxygen come from?
 * If I recall correctly there are massive air scrubbers underneath the surface that provide the Oxygen to the people living there. I've only read NJO, but I think I remember some of the people going down into one at some point. --Ctachme 23:16, 15 May 2005 (UTC)

Subsection: The Fall of Coruscant
It might be useful to divide the History section up into subsections, which could provide easy linking to specific parts of Coruscant's history, including the Fall of Coruscant. It might also be useful to include more information on the fall of the planet. I am currently at work assembling some information on this historic event. – Mipadi June 28, 2005 15:26 (UTC)

In one story they turn off the air scrubbers, and expanded universe story...a rouge squadron one, or maybe Mara just mentioned that Palpatine enjoyed being incontroll of the air scrubbers to suffocate the population

I think we really need to cut back on the indepth nature of this article. Remember, it is all fiction.Johnpacklambert 00:34, 27 July 2007 (UTC)

Original surface streets
I've been curious for a long time about what's at the absolute bottom of the planet. The "surfaces" we see at the beginning of EP3, where starships crash, are far above the actual, original ones. We can see crevasses all around, so those "surfaces" we see up top are actually artificial plateaus or mesas. If one could fly down those crevasses and to the first 25 levels, what would things be like down there?

Don't say "pitch black". The airspeeder's lights are on. So are the infrareds and nightvisions. --Shultz 05:08, 15 November 2005 (UTC)

We're going to see more of Coruscant in the upcoming Star Wars: 1313 game. Looks pretty good. I'm sure it'll end up adding more info to this page. Venku Tur&#39;Mukan (talk) 22:59, 29 August 2012 (UTC)

Coruscant's Skyscraper Height
Since this city-planet is based in a futuristic setting their building's should be seriously high, im asking if anyone knows the average building height or the tallest in the city planet. taking in note that todays tallest Skyscraper is the Taipei (1,670)Enixspirit 23:27, 13 April 2006 (UTC)EnixSpirit

Most EU uses "several kms" but the Han Solo Trilogy has Han going down over a thousand levels to reach the bottom, so that would be at least 3km or so.

The tallest building now is The Burj Dubai, roughly half a kilometre tall but projected to reach 0.8 km. Inflaton85.211.1.109 17:41, 31 July 2007 (UTC)

Etymology and Naming
I have heard that there may also be a connection to Khorasan. Apart from the obvious similarity of the names and pronounciation, there is also some parallels to Islamic Themes, see here: http://www.altmuslim.com/perm.php?id=1473_0_25_0_C —Preceding unsigned comment added by 84.63.30.18 (talk • contribs)


 * I would question some of the theories at the link. Jedi also look like ancient Jewish Prophets.


 * I greatly doub it. That's a bit of a stretch, and a derivation from "coruscating" (or, "coruscant"; as in, "The coruscating gem was coruscant.") is much more likely. --maru  (talk)  contribs 02:19, 10 May 2006 (UTC)


 * Er, life before Star Wars. The Wiki article itself says the earliest use of this word in the Star Wars universe was in a book in 1991.  I know in 1996 or 1997 I received an email from a gentleman interested in starting a small, close-knit discussion community he titled "coruscant".  I suppose it is indeed possible that he was pulling from SF fandom, but he didn't seem the sort...  A quick check of Meriam Webster's website  reveals coruscant is a normal old adjective meaning 'shining' or 'glittering'.  Further, Yahooligans gives a more thorough definition and confirms  the same etymology as found in the Wiki writeup.  Finally, a Google search for phrase "the word coruscant"  finds several sites referring to the author E. E. Smith whose use of the word in his 1920s SF is likely what resulted in the planet's naming in Star Wars.  Everything old is new again. OldMiner 15:05, 10 August 2006 (UTC)


 * That is only a possible connection if you can show anyevidence that Zahn ever read the works of E. E. Smith. Just because there are books in the world does not mean they influence latter writters.  I have never heard of E. E. Smith before and am not convinced that you had until you googled the subject.

I seem to recollect of Star Wars (the original film) Obi Wan being worried about Leia being diverted or possibly taken to "The Imperial planet of (or palace on) Coruscant". It could be from The Empire Strikes Back. I'm not sure. Anyone here have a better memory of that sequence? I know it wasn't from the Return of the Jedi. —Preceding unsigned comment added by 71.13.148.189 (talk) 17:38, 8 November 2007 (UTC)

Might someone be able to locate the earlier sources that call Coruscant as Jhantor? To my knowledge, Timothy Zahn introduced the name in his famous Thrawn trilogy. But I can't find the reference. Gieskanne (talk) 11:53, 13 October 2021 (UTC)


 * Happy this thread already exists there is something very obvious about the name. Greater Khorasan. It is identical and Star Wars does draw from without ever giving credit to where it draws from. Yes some of the themes look like Ancient Jews, but a lot of the aesthetic is clearly Islamic. Hausa warrior (talk) 07:32, 20 October 2022 (UTC)

Reminiscent of Earth?
Do you guys think George Lucas made Coruscant to hint the future of Earth? --KFan II 16:57, 13 May 2006 (UTC)

Diameter
Ok, I'm a little confused about something. In the info box, it says something about the diameter of the planet being 1,444km in relation to its potential population being 2.8 Trillion people, which in all reality would be impossible to house a civilization like this. For instance, the diamter of earth is something like 12,000km. Furthermore, Wookiepedia lists the diameter as 12,240km. So I was just wondering where this 1,444km came from or am I just missing something here? (Grizzwald 19:55, 18 February 2007 (UTC))

our moon is bigger than 1,444 km. Why is this figure here? and earth is bigger than coruscant  — Preceding unsigned comment added by 24.217.70.184 (talk) 19:33, 16 November 2013 (UTC)

Coruscant Year?
"Galactic Standard Time was developed on Coruscant and revolves around the hours Coruscant has in a single day, which is 24 hours, with 368 local days a year." This seems to contradict the Dates in Star Wars article, which states that the days have something like forty hours of twenty-three minutes. I assume that the dates article is correct, but could someone verify that?--76.23.84.86 01:57, 30 June 2007 (UTC)

Coruscant being Taris
In the History section it says there is speculation that Coruscant is a rebuilt Taris. How can this be considered valid? There are references to Coruscant in Knights of the Old Republic like when a Sith Soldier on Maanan says that the Sith will eventually conquer Coruscant. So how couled Coruscant be Taris? 71.221.220.143 03:49, 5 July 2007 (UTC)
 * Stupid, ignorant fanwanking. Taris is in the Outer Rim, Coruscant is a Core World. They're referenced in several different sources as distinct planets, including at least two official maps. I could write a longer rebuttal, but it's just a waste of time. - Sikon 01:24, 6 July 2007 (UTC)

The adjective name...
The article reads in the introduction: "The adjective form of the planet name is Coruscanti."

Is there any canonical source that states this? The sentence seems like some sort of joke...

 * I think I've heard this somewhere but I don't remember what it was in. It may just be generic fan-talk or it might have been in the Clone Wars animated series on Cartoon Network. Venku Tur&#39;Mukan (talk) 22:54, 29 August 2012 (UTC)

"The word "coruscant" is also a French adjective which can be used to describe a decadent and overcomplicated language, decorum or community."

coruscan, ante adj, is a french adjective alright but it has only one meaning, and it is not decadent or anything else it just mean shiny. The author must have mistook it for condescendant, ante adj which simply mean patronizing.

 * I would add that across wikipedia, the phrase "adjective form" is typically replaced with demonym, also referred to as a gentilic 173.73.137.96 (talk) 11:00, 11 September 2009 (UTC)

This sentence was just removed: ..because it would not provide a "reliable source". Are you kidding?

 * "Another connotation leads to Khorasan, a central asian region marking historic touches between the arabian and asian civilisations."
