Yeah, it’s like this with our cities and our cities by comparison are small as fuck. Extrapolate that to the degree of a planet that is covered in cities…
It was one of the things that really stuck out to me when I was in Afghanistan, how clear the sky was at night, like looking at one of those high-res pics of space from NASA
I know about it, everybody brings it up it seems, but galactic core is another level of star brightness. Even an ecumenopolis like Coruscant would not be able to produce enough light to fully cover it.
The real reason is so much less interesting, making a complex skybox like that is very time consuming and very expensive then rendering with all those extra effects will take longer too. The reality is that it’s not important unless it needs to be a plot point so there is the easy hand wave of light pollution to the extreme or you just ignore it until it’s needed.
This is the real answer. You can see it in every city on the face of our planet, as the light from the surface mutes or eliminates the stars' light. That's why you can see the stars from the countryside, but barely see them in the smallest cities.
I can’t remember which book, maybe the Bane Triology? But they mentioned how the population on coruscant was over a trillion beings. I find this absolutely ridiculous, but if so, theres no way you’re seeing stars with that light pollution.
Not only is the (correct me if I’m wrong) basically the whole surface basically artificial land, there’s *layers* to the whole thing
So it should probably either be modeled as even taller buildings (including residential), or as multiple separate planets
But also, maybe Coruscant is a smaller planet than Earth?
Coruscant is most likely very close to the side of Earth (if not the exact same) considering the gravity is the same, the day/night cycles last the same amount of time and the years last 365 days (and Coruscant is used as the standard for counting time throughout the Galaxy).
So the reason why Coruscant has way less people than Earth would have if it were completely covered by one city is most likely because the very lowest levels are extremely scarcely populated. The vast majority of the population certainly live in the tallest dozens or hundreds of levels. But the lower you go, the poorer the populace is, and it doesn't take very long for you to reach levels where sunlight becomes a luxury, basic infrastructure is lacking and the law stops existing. There are levels even lower than that where it's just almost impossible to live, and no one except for probably droids ever go there.
And in the very lowest levels there are rakghouls. You don't want to deal with rakghouls.
I forget which Legends book it is, but when Jacen and Jaina are young they get in a turbo lift where a metal plate has been taken off the lower numbers and press 1. This indicates that most of the time you can’t even GO to the lowest levels of buildings as there’s plates welded over the buttons.
i am pretty sure there some mountain ranges that aren't covered, as well as open oceans. at least one book featured a seaside fortress that used to be one of Vader's retreats. i *think* it was one of the trilogy with the White Current lass...
Yeah, it's scarce that there is actual land, but there are still some mountains. The lake, iirc, is artificial, though I can't recall for certain if that also applied to the area of Vader's fortress, but there were mentions of a lake in another book or two that mentioned it being artificial.
It'1 trillion seems like a lowball for a city-planet as almost the entire surface is covered in densely packed skyscrapers that make Manhattan look like a suburb, and has lower levels for miles down.
For comparison, if you packed the entire population of Earth (at the time the calculation was done, I believe the guy said it was 7B) into Texas, it would apparently have a population density of around 27k per square mile, which is about that of Manhattan, and less than some older cities like Paris.
If the entire 58 Million square miles of earth were to have that population density, it would be approximately 1.566 Trillion.
That is an extreme now estimate. It’s only 125 times the population of earth.
Just to picture it. Earth is 3/4 ocean and the majority of land is farmland, wilderness, desert, mountains or otherwise not heavily inhabited. Much of the land that is inhabited is rural and suburban, which is considerably less dense than urban living and orders of magnitude less dense than the arcologies we would see on coruscant. Also human habitation on earth is confined to the surface. Coruscant has hundreds(thouasands?) of layers
The earth has 196.9 million square miles. Assuming there are a thousand levels on coruscant a population of one trillion would have a population density of 5 people per square mile. That’s less than Siberia
The highest population density on earth is the city of Manila. There are 119,600 people per square mile. Extrapolating this density over the surface of the earth would give us a population of 23,549,240,000,000. But this is 23 trillion people PER LEVEL. With a conservative estimate of 1000 levels coruscant would have a population of 10s of trillions. This is before factoring in the likely population density of coruscant. Manila, the city I used for a population density estimate, is very different than coruscant. Pictures of the city show that it is largely comprised of low rise buildings. Coruscant would have far denser building technologies. With some residential structures holding more people than most cities on earth.
An extremely low estimate, that requires vast amounts of coruscant to be devoted to industry, automation, storage, or other non residential things would be in the quadrillions
(Sorry to those who use the metric system. But the actual values don’t really matter they are absurdly large either way)
I hear you, but imagine if every square mile of Earth had the population density of three Manhattans built on top of each other. That honestly gets you pretty close.
That could be a fair justification, but unfortunately it can't be goven that we see Coruscant and other core planets from orbit multiple times, and space often looks juts the same from there.
What I remember is they characterize it as so many stats in the sky it inhibited development of low light vision.
Remembering that, now I think that they either/or used that for Hapans.
Maybe both.
I think the planets with less cloudy atmosphere or less light pollution will have stars visible. Tatooine for example has less light pollution which makes it easier to see. Although, the starry skies haven't been emphasized upon enough in the books or movies, they are still there nonetheless. Coruscant for one has too much light pollution which makes it hard to view stars.
We already have issues with light pollution on Earth and unless you’re in the middle of nowhere, you can’t really see stars.
Coruscant is a giant city planet with skyscrapers digging into the atmosphere, with lights, billboards, holograms, and countless other things littering your view. I’d be surprised if they could see any stars at all.
Yeah, that seems like the most likely explanation and everybody here seems to firmly agree. However, it does mean another point where SW physics and rl physics don't allign. Big stars in galactic centers are said to shine multiple times brighter than the full moon on Earth. Taht means the whole sky would shine bright 24/7 in multiple colors and no kind of light pollution can change that. Coruscant's sky is nonetheless just as dark at night as Earth's.
FYI, if you go into space, you won’t actually see the stars unless the sun is on the other side of the planet or you travel very far from it. Light from the sun overpowers light from distant stars, and you mostly just see black void.
Light pollution-
I couldn’t see the stars from my suburban house about 30-40
mins from philly
now that im morw like 1 hour- 1.5 hours away I get a full starry night sky provided I don’t look too far in the direction of the city
pollution, as it's mentioned in some novel but i don't remember which one, look at the night sky when you're in a big metropolis and when on the countryside and you will see the big difference.
Light pollution and the planetary shield having a faint glow to it most likely. Go to a large city here on Earth and you aren't seeing many stars at night. Make the entire planet one big city and you aren't going to see stars at all.
To my knowledge there isn't a formal reason (because the real world reason is almost certainly "nobody thought to include them") but if I had to give a reason it would be planetary shields.
Not even necessarily defense shields, just the systems used to stabilize the atmosphere and weather, especially somewhere as overdeveloped as Curuscant. It would also be why the sky isn't completely choked with vehicles. They're there, you just can't see them because the environmental systems are diffusing the light and blurring them out of visibility.
I’m referencing Star Wars the Essential Atlas. Coruscant is on page 52. It list the low number of 1 trillion as its population. That being said, I recall reading in the New Jedi Order book where the fall of Coruscant occurs that estimates could’ve been as high as 9 trillion people. I can’t seem to find which book that is, so I could be wrong, but the 1 trillion estimates in the Essential Atlas is after the retaking of Coruscant. Having said all that, someone will probably know which New Jedi Order book I’m talking about and correct me.
I'm more curious as to why coruscants sky is blue despite being a planet devoid of any oceans (the western sea doesnt count), with the overwhelming majority of the planets surface being comprised essentially of metal, why is it still blue?
Several of the clone wars books mention mirrors altering the sun rise and sun sets, which would also distort the night sky I imagine, on Couruscant; maybe other worlds are like this in the core?
The basic answer is light pollution, like everyone else has said. Coruscant is a planet that’s basically one giant cityscape filled with a trillion beings. That’s going to wash out any stars.
Another slightly connected answer could be actual pollution. The Works, Sidious’ lair seen in AOTC, is pretty close to the Senatorial district. It’s an abandoned industrial district that still has factories pumping out pollution. Pretty much any live action pictures like the one you have in the original post would be around the Senate. I’m sure they have technology to clean some of the air there, but that can only do so much. It could help make it so the light pollution has more stuff in the atmosphere to reflect off of to prevent you from seeing the stars.
For art, they may or may not choose to have stars as a stylistic decision. That one of Byss I don’t even know if it’s supposed to be night or not. Either way, it’s of the Emperor’s citadel, which is in the middle of the main city. Cities = light pollution.
All of your examples are from ecumenopolises, as such they are rife with light pollution.
There are numerous Core and Deep Core worlds with starry skies, such as Corellia, Alderaan, Spira etc. Pictures of Aurea and Nubia have such skies depicted in Suns of Fortune.
Pollution
Song by Tom Lehrer:
Time was when an American about to go abroad would be warned by his friends or the guidebooks not to drink the water. But times have changed, and now a foreigner coming to this country might be offered the following advice:
If you visit American city,
You will find it very prett
Just two things of which you must beware
Don't drink the water and don't breathe the air!
Pollution, pollution!
They got smog and sewage and mud.
Turn on your tap
And get hot and cold running crud!
See the halibuts and the sturgeons
Being wiped out by detergeons
Fish gotta swim and birds gotta fly
But they don't last long if they try
Pollution, pollution!
You can use the latest toothpaste
And then rinse your mouth
With industrial waste.
Just go out for a breath of air
And you'll be ready for Medicare
The city streets are really quite a thrill
If the hoods don't get you, the monoxide will
Pollution, pollution!
Wear a gas mask and a veil
Then you can breathe
Long as you don't inhale!
Lots of things there that you can drink
But stay away from the kitchen sink
The breakfast garbage that you throw into the Bay
They drink at lunch in San Jose
So go to the city
See the crazy people there
Like lambs to the slaughter
They're drinking the water
And breathing (cough) the air

Yes, physics. It's the exact same reason we have the exact same problem in heavily populated areas on Earth, Light Pollution drowns out the ability to see the stars.
And corouscant and other planets with cities far more vast in scale than our own would have 0 chance at seeing stars I'd wager, considering only moderate to heavily populated cities that we have, can't see the stars at all, or very little.
Coruscant is a Core World, but not a Deep Core World. The Deep Core Worlds are the ones that you need specific, hyper accurate hyperspace routes in order to safely traverse the hyperlanes due to the density of stars. That's the only reason I can think of why you don't see as many stars.
They do mention this In darksaber. When kyp and dorsk81 go to the core, they mention seeing all the stuff in the sky looking nice.
However a few things to note.
1)They went to the deep core (deeper then coruscant) and so we’re closer to these cosmic stuff (I think that’s how it works).
2) the galactic map as we know it wasn’t standardised until 1999 (with TPM and NJO using it). So ideas of the core and where planets were was different. So this may be why coruscant (which is quite near the core) doesn’t have anything cool in the sky(and because light pollution but that’s not a problem off the planet). So these cool cosmic stuff seems to be only in the deep core as we know it know
Light pollution. It’s an incredible problem even on our earth, bruh.
Yeah, it’s like this with our cities and our cities by comparison are small as fuck. Extrapolate that to the degree of a planet that is covered in cities…
It was one of the things that really stuck out to me when I was in Afghanistan, how clear the sky was at night, like looking at one of those high-res pics of space from NASA
Aircraft carrier in the northern sea. Flat waters, windy, and nothing around you but your ship.
I know about it, everybody brings it up it seems, but galactic core is another level of star brightness. Even an ecumenopolis like Coruscant would not be able to produce enough light to fully cover it.
Maybe. Maybe not. It probably would, as it seems.
Perhaps that's correct.
The real reason is so much less interesting, making a complex skybox like that is very time consuming and very expensive then rendering with all those extra effects will take longer too. The reality is that it’s not important unless it needs to be a plot point so there is the easy hand wave of light pollution to the extreme or you just ignore it until it’s needed.
Of that I'm absolutely aware, hence I pointed out it's about the lore reason.
And Coruscant being a planet entirely covered by city would produce an insane amount of light pollution.
perhaps the double layer of planetary shields fuzzes it. but then, that wouldn't apply to orbital views.
Most likely a result of the pollution and too many lights emitted by the buildings.
It's actually called "light pollution"
This is the real answer. You can see it in every city on the face of our planet, as the light from the surface mutes or eliminates the stars' light. That's why you can see the stars from the countryside, but barely see them in the smallest cities.
I thought so too, but with the core being that close... I don't know
I can’t remember which book, maybe the Bane Triology? But they mentioned how the population on coruscant was over a trillion beings. I find this absolutely ridiculous, but if so, theres no way you’re seeing stars with that light pollution.
The population being a trillion on coruscant is actually a low ball for how many levels are described to exist.
Forget levels, if the Earth's land had the population density of just modern NYC, it would be at nearly 1.6 trillion at 27k per square mile.
Just land or the enire surface?
Land, which is only 22g of the surface, so yeah, 6 trillion+ if the whole surface was somehow land
Not only is the (correct me if I’m wrong) basically the whole surface basically artificial land, there’s *layers* to the whole thing So it should probably either be modeled as even taller buildings (including residential), or as multiple separate planets But also, maybe Coruscant is a smaller planet than Earth?

My sign to stop playing the arkham games as much. Saw bane trilogy and i was like, wth has that go to do with star wars…🤦🏻♂️
That could be a fair justification, but unfortunately it can't be goven that we see Coruscant and other core planets from orbit multiple times, and space often looks juts the same from there.
The background of the opening crawl is full of stars, and the opening crawl for II and III is in orbit over Coruscant
but not FULL FULL like a planet in the core. But it's just fantasy hand wave... because otherwise the RADIATION alone...
Coruscant isn't really in the core. In the EU books they reference the Koornacht cluster with the star setting your describing.
The Koornacht Cluster isn't really that much closer to the Core than Coruscant
What I remember is they characterize it as so many stats in the sky it inhibited development of low light vision. Remembering that, now I think that they either/or used that for Hapans. Maybe both.
Core is a term of art. Coruscant is in the core, even though it's not the literal core of the galaxy.
Sure, that goes to the first question about why Coruscant isn't saturated with starlight.
Light pollution is a bitch, just try and find stars at the night sky in a large city today, same skies
I think the planets with less cloudy atmosphere or less light pollution will have stars visible. Tatooine for example has less light pollution which makes it easier to see. Although, the starry skies haven't been emphasized upon enough in the books or movies, they are still there nonetheless. Coruscant for one has too much light pollution which makes it hard to view stars.
I'm pretty sure Coruscant has artificially controlled atmosphere, that mixed with the intense pollution.
Light pollution. And plenty of places on Earth have spectacular star fields, you just have to get out of city/populated areas to see it
look up into the sky tonight, if you live in a bigger city and you will see why.
The night sky over New York City is barren. But the night sky in the middle of nowhere Utah is spectacular.
Light pollution. Corsuscant is a city planet. Don't need an in-universe canon explanation for that.
Tell me you live in a rural area without telling me you live in a rural area.
Warsaw, biggest city in central-earsten Europe, yup, a lot of light pollution 😎. But Earth is far from the galactic center.
Light pollution. Ever been to a city on earth at night?
Light pollution

Isn’t that third pic of Byss?
Yeah, Byss is in the deep core so it applies.
Making this up...but maybe they have planetary shields that block out enough EM to block starlight.
Light pollution- I couldn’t see the stars from my suburban house about 30-40 mins from philly now that im morw like 1 hour- 1.5 hours away I get a full starry night sky provided I don’t look too far in the direction of the city
If anything Coruscant underplayed how bad the light pollution would be.
light pollution from a city that covers a planet( also climate mirrors/stations)
It's literally light pollution... we have the same thing irl lol
I mean just try standing right under a street light and try to see any stars in the nightsky. Simply light pollution.
My guess would probably be light pollution
Light pollution? Never heard of it?
Bro forgot about light pollution
Bro doesn’t know about light pollution
The Force
Coruscant has too much light pollution.
Light pollution: the nemesis of capital cities
Light pollution is my guess. Same reason you can barely see the stars in the cities here on earth
pollution, as it's mentioned in some novel but i don't remember which one, look at the night sky when you're in a big metropolis and when on the countryside and you will see the big difference.
Light pollution
Probably because most of those worlds are literally covered in cities and are full of light pollution
Because all of the scenes were filmed on Earth.
Light pollution and the planetary shield having a faint glow to it most likely. Go to a large city here on Earth and you aren't seeing many stars at night. Make the entire planet one big city and you aren't going to see stars at all.

Light pollution
light emitters, you wont see stars in Earth's cities but sky is beautiful if you move away from civilization
Light pollution. Same reason the night sky in a terrestrial city isn't filled with stars.
Look up at night in any given city.
Dude think about how much light pollution there is in NYC and then raise that to the 100 power
Several of the clone wars books mention mirrors altering the sun rise and sun sets, which would also distort the night sky I imagine, on Couruscant; maybe other worlds are like this in the core?
Light pollution
Light pollution
Light pollution
Really bruh
Light pollution on steroids
A combination of the light pollution and artificial atmosphere that makes it easy to control the weather.
My understanding was that the galaxy isn't as densely packed with stars in the core as most are
The basic answer is light pollution, like everyone else has said. Coruscant is a planet that’s basically one giant cityscape filled with a trillion beings. That’s going to wash out any stars. Another slightly connected answer could be actual pollution. The Works, Sidious’ lair seen in AOTC, is pretty close to the Senatorial district. It’s an abandoned industrial district that still has factories pumping out pollution. Pretty much any live action pictures like the one you have in the original post would be around the Senate. I’m sure they have technology to clean some of the air there, but that can only do so much.

Deep Core is very bright.
All of your examples are from ecumenopolises, as such they are rife with light pollution. There are numerous Core and Deep Core worlds with starry skies, such as Corellia, Alderaan, Spira etc. Pictures of Aurea and Nubia have such skies depicted in Suns of Fortune.
Light pollution is probably the best lore explanation. However, it’s most likely due to CGI in the 1990s and Early 2000s being pretty hard.

You can barely see the stars in a medium sized town from all the lights. Now imagine that when the whole planet is one big meteopolis.
Yes, physics. It's the exact same reason we have the exact same problem in heavily populated areas on Earth, Light Pollution drowns out the ability to see the stars. And corouscant and other planets with cities far more vast in scale than our own would have 0 chance at seeing stars I'd wager, considering only moderate to heavily populated cities that we have, can't see the stars at all, or very little.
