I’ve been watching Generation Tech lately, a YouTube channel that covers Star Wars lore, usually revolving around the space tech and tactical doctrine or logistical efforts of the wars in the stars, i.e. what is an AT-AT’s purpose on the battlefield and why is it designed the way it is (answer: It’s a platoon-size IFV designed to be level with the skyline in most cities so that rebels can’t get above it, which makes it more intimidating, as per the Tarkin Doctrine).
One thing that keeps coming up in an annoying way is that the Star Wars galaxy has a million or more habitable planets. This leads to things like the Imperial Navy having 25,000 star destroyers at its height, and that’s for a navy that’s stretched thin, only able to directly occupy 2.5% of the planets they nominally govern. While it makes sense that they can’t mobilize the whole navy to go to Endor because they need some for patrol duty and occupation of trouble spots, it makes the battle seem pointlessly small if the entire Rebel Navy is there (Palpatine expects the Rebellion to be pretty much finished if they lose), is badly outmatched by the Death Squadron of star destroyers, and Death Squadron is struggling to reach 0.1% of the size of the total Imperial Navy.
Star Wars generally uses planets as though they were small countries: They have a single important city on them surrounded by lots of sparsely populated rural or frontier countryside. There’s clearly lots of small towns and countryside on Naboo, but the only major city we ever hear about is Theed, which is a pretty mid-size city. There’s probably other cities on the planet, but not many, and no megalopolises like Tokyo or New York City that we have here in our one-planet civilization. The Organa family might live in the countryside apart from major cities (medieval and Renaissance aristocrats did this, and they’ve kind of got that vibe), but certainly what we see of Alderaan (a core world!) suggests that there are like twelve cities total on this planet and they’re all pretty small, with forests for child princesses to impulsively wander off into within easy walking distance. Kashyyyk doesn’t seem to have any major cities at all, just small towns and villages peppered across the planet. Coruscant leaps to mind as an exception, where the parts we see are a small country centered on the Senate and Jedi Temple but there’s definitely a very densely populated entire planet beyond that, but there’s not many planets like that.
And if planets are like small countries, there’s only 200-ish countries on Earth, and even accounting for the fact that some of those countries are big countries that would be represented by multiple planets in Star Wars (space California and space Texas could be smushed together into one planet, but you wouldn’t expect it to be), 1,000 habitable planets is more than enough to cover everything Star Wars needs to. Yes, this means only a puny fraction of planets are habitable, but that was already the case. The Star Wars galaxy is about the same size and shape as the Milky Way, which means there are hundreds of billions if not trillions of planets in it, which means even the highest numbers given for the habitable number (“millions”) is well under 0.01% of the total. Since habitable planets are super rare no matter what, let’s cut them down to a number that’s both big enough that we’ll never plausibly outrun it when making up new planets yet also small enough that it’s believable that a battle for one planet matters.
The only reason Star Wars media is anywhere near exceeding a thousand named planets is because people keep inventing new planets unnecessarily. The mainline movies, TV shows, and video games do not do this, and while I’m less familiar with them, I can’t imagine the novels or comics are doing it that much. There’s like a thousand issues of Star Wars comics total, across all of time, so in order to run out of planets they would have to be introducing about one new planet per issue, which they don’t, and there’s only about 400 novels. Novels are more likely to introduce a new planet or even several than comics because they’re longer stories, but also a lot of the “novels” are actually YA books which visit fewer planets because they aren’t that much longer than a single issue of a comic. Plus, most of these stories reuse some of the 100+ planets already established rather than make new ones up.
And at this point an emphasis on reusing planets instead of making new ones up would serve Star Wars pretty well. It’s pretty telling of JJ Abrams’ flaws as a Star Wars creator that he felt like he needed to invent new planets, but the best he could come up with was Jakku, which was Tattooine with a “welcome to Jakku” sign slapped on. The only reason Jakku needs to be a separate planet from Tattooine is because of its backstory, which was not referenced by the movies in any way. Jakku is a mid-rim planet between Endor and Coruscant and the site of a battle between the Rebellion and the Empire in the aftermath of Endor, which is why there’s all these defeated Imperial wrecks lying around.
As far as I can tell this backstory was created by people trying to contrive reasons why this place that is clearly identical to Tattooine could justifiably be a new planet, and all they could come up with is that it is located in a different part of the galaxy. Sometimes that’s justified. Hoth and Rhen Var are both ice planets, Rhen Var has mountains but so what? Hoth could’ve had some mountains on it far away from Echo Base. But Rhen Var also has Sith ruins on it, which means it’s in ancient Sith space, like Yavin 4. If they put those ruins on Hoth instead of making a new planet, that means ancient Sith space covered most of the galaxy. If they moved Hoth to be closer to Yavin 4, that means the Rebels’ secret backup base was pretty close to their original secret base which makes them look like a regional nuisance, not one side of a Galactic Civil War. Rhen Var legit needs to be a new place even though it’s an uninhabited ice planet just like Hoth, purely because of the astrographic implications of Hoth having a Sith ruin on it.
Jakku, though? Sure, if the Battle of Jakku happened between the Battle of Endor and the Rebellion capturing Coruscant then it needs to be in the Mid Rim. But there’s no reason for the timeline to be like that, and Jakku has really strong Outer Rim vibes and is also clearly just Tattooine with a crashed star destroyer on it. So here’s a better backstory for Rey on Tattooine: The Battle of Endor is in the year 4 ABY. Rey was born in 15 ABY. The Battle of Starkiller Base is exactly 30 years later, 34 ABY, when Rey was about nineteen (about the same age as Luke at the Battle of Yavin). This is all from the existing canon, so how can we fit a Battle of Tattooine in to leave a star destroyer lying around for Rey to scavenge there by 34 ABY?
In the immediate aftermath of the Galactic Civil War, the New Republic fought on-and-off regional wars with Imperial remnants, especially in the Outer Rim. The Outer Rim had always been mostly de jure independent and after consolidating the Core and some key Rebel planets like Mon Cala, the New Republic was mostly willing to play nice with Imperial remnants in other parts of the galaxy, especially the Outer Rim, but sometimes those Imperial remnants poked the New Republic, resulting in a small war. In 14 ABY, ten years after the Battle of Endor, an Imperial remnant fleet caught up in one of these regional wars had fled to Tattooine and made their last stand against New Republic forces there. Because of the remote location of the battle, the New Republic never bothered salvaging the Imperial wrecks. They didn’t want Tattooine, they just wanted to make sure this specific fleet would not make incursions into Republic space again, so job done, they leave.
Scavengers descend on the planet to salvage advanced, military-grade Imperial technology like turbolasers and AT-AT cannons and twin-ion engines. Rey’s parents meet during this gold rush and have a kid in 15 ABY. Two or three years later, the really valuable stuff is gone, and Rey’s parents leave the planet. Unable to afford a kid now that the gold rush years are over (and having squandered all the money they made during the gold rush on living large), they leave her as well. The Imperial wrecks are still full of lighting fixtures and regular old power conduits like the kind they sell for twenty credits at Space Target, because the gold rush scavengers walked right past all of those to get to stuff that cost tens of thousands, hundreds of thousands, or millions of credits to build, which could be salvaged for a year’s worth of pay even at pennies on the dollar. What’s left is still enough to make a respectable living on if your standard for “respectable” is moisture farmers and cantina rats, but it requires spending all day scavenging half-functional parts worth just one or two credits each. Nobody wants to live on Tattooine and the people who already live there mostly already have jobs that are less dangerous or more profitable (in the latter case, because of crimes), so even fifteen years later there’s still some salvage left if you know where to look (star destroyers are big), but the last few scraps are finally starting to get picked clean. Open the curtain on Rey in 34 ABY.
I think Star Wars creators are in the habit of adding in one-off planets because this helped make the galaxy feel very big and believable for a long time. Han Solo makes a one-off comment about a bounty hunter on Ord Mantell and it helps make the galaxy feel like there’s more to it than just what was purpose-built for our protagonists. But we’re long past the point where adding in more and more planets makes the galaxy feel believably large and have reached the point where new planets make the galaxy feel unbelievably large, so large that it’s difficult to see how our protagonists could possibly be having an impact on it. The Galactic Senate chamber is not big enough for a million worlds, the Rebel fleet at Endor is not big enough to stand a ghost of a chance against 25,000 star destroyers even given a descent into chaos following the death of the Emperor, the Battle of Christophsis can’t possibly be significant for a war between factions that each control hundreds of thousands of planets.
Back in Empire Strikes Back, Star Wars had already established the significance of individual planets (roughly equivalent to a small country), but had only named Tattooine, Alderaan, Dantooine, Yavin IV, Hoth, Bespin, and Dagobah. So when Han Solo needs a throwaway line about an encounter with a bounty hunter shaking him up, it’s a good idea to drop a one-off reference to Ord Mantell, some planet we’ve never heard of before and which there are currently no plans to use in any movie or spin-off material. There’s at least a few hundred and probably about a thousand planets out in the galaxy, when we’ve named a grand total of seven of them, the odds that any random planet referred to would be one of those seven is struggling to reach 1% even before considering how remote and backwater most of those planets are. But that was a long time ago. We have hundreds of Star Wars planets now, so it’s not weird that when one comes up, it tends to be one we’ve already heard of.
