Galactic Outline...

The Star Wars Galaxy is made up of millions of planets in hundreds of thousands of sectors in dozens of regions of the Galaxy. The main areas of the Star Wars Galaxy are the Galactic Core, the Outer Rim and the Unknown Regions. Many of specific areas, such as the Corporate Sector and the Inner Galactic Core exist, but for the purposes of this section we'll ignore these divisions and simply list planets alphabetically. Each planet will have a percentage bundled with it. This percent is equivalent to the chance we give this planet of making it into SWG. We use the following guidelines when assigning a percentage:

100%: We know the planet's going to be in Star Wars Galaxies.
90% - 99%: It fits all the 'requirements,' and there have been subtle hints dropped by the devs.
70% - 89%: There is a very good chance this planet will make it into SWG.
50% - 69%: This planet is well known and diverse enough to possibly make it into SWG.
25% - 49%: Not enough is known about this planet to make it into SWG, but it's still possible.
1% - 24%: There is very little chance this planet will be included in SWG. Most planets fall under this category.
0%: There is exactly no chance that this planet will ship with SWG. Duh.

Without further adu, let's get started...

Planet Listings:

(By Percent Chance, then Alphabetically) [Click here for Alphabetical list]

Corellia: Corellia is a planet near the core systems. It has long been known as the birthplace for some of the best smugglers and pirates. Through it's shady reputation, though, is a beautiful planet, full of amazing canyons and spectacular vistas. The infamous Han Solo is from Corellia. Corellia was released as a known playable planet during the first Developer's Chat.
Chance: 100%

Endor: [One of the most confusing Planet/Moon combinations in the Star Wars Galaxy, I've come to the conclusion that Endor is actually the planet, and the object holding the 2nd Death Star's shield generator was the planet's moon. Someone correct me if I'm wrong.] Endor's moon holds a temperate climate, and is home to the furry and amusing Ewoks. The Ewoks are extrememely superstitious. It is said that many beasts and dangers roam the vast forests of the moon. Endor was released as a known planet during the second Developer's Chat.
Chance: 100%

Lok: First appearing in the video game Star Wars Starfighter, Lok was also featured in it's sequel, Jedi Starfighter. A sulfuric planet, it's surface is mostly wasteland. Lok is populated by multiple less-then-savory clans, and has thus become known as a 'pirate planet.' Lok is located between two major trade routes in the mid-rim, which 'makes it the perfect staging ground for assaults on shipping vessels.' (Shug Ninx). Lok was announced as a planet in late July, 2002.
Chance: 100%

Naboo: Naboo is a lush, diverse planet near the Outer Rim. It is home to at least two known sentient species, the Naboo (Humans) themselves and the aquatic Gungans. Naboo was home to the Trade Federation blockade that saw the first signs of deceit from the then noble Senator Palpatine. Naboo is also home to Queen Amidala and the ever lovable (can you sense my sarcasm?) Jar Jar Binks. Naboo is also covered by a large number of diverse species and a dozen or so differing habitats.
Chance: 100%

Rori: Rori is a moon orbitting Naboo. It will share many characteristics with Naboo itself, and is colonized mostly by humans. Other then that, little is known. Rori was announced as a 'planet' during the 5th developer's chat.
Chance: 100%

Talus: Talus is one of the Twin Planets in the Corellia system. It and it's sister planet, Tralus, orbit the ancient Centerpoint station. Talus is similar in fauna to other planets in the system, such as Corellia, yet it's expansive mud flats and sharp ravines distiguish it from it's close neighbors.
Chance: 100%

Tatooine: Tatooine is a hot desert planet in the Outer Rim of the Galaxy. Tatooine was settled by miners hoping to strike it rich on the many precious metals thought to be buried beneath it's deserts. Alas, they didn't find anything, and many of them headed coreward, leaving their great Sandcrawlers to be taken over by the scavenging Jawas. Since that time, Tatooine's future hasn't really gotten any brighter. Moisture Farmers scour it's surface for water to sell in it's many spaceports, such as the infamous Mos Eisley and Anakin Skywalker's hometown: Mos Espa. The Boonta Eve Classic is also a popular tourist draw, with the pod-racing contestants speeding around the challenging course at breakneck speeds. Tatooine is inhabited not only by the human settlers, but also the pre-mentioned Jawas and a vicious race of Sand People, also known as Tuskans. Dangerous sand storms and fearsome predators such as the giant Krayt Dragon make travelling outside the sleazy spaceports and cities a challenge for even the most seasoned explorers.
Chance: 100%

Yavin: Yavin is a gas giant planet in a star system of the same name. It is located in the outer-rim territories. Yavin has over two dozen moons, and is also the only place in the galaxy where Corusca gems can be found naturally. Yavin IV, one of it's moons, once housed a rebel base during the reign of the first Death Star. Unknown to the rebels at the time, the ancient temples that housed the base were great sources of power for the evil Sith Jedi Exan Kun. Seven years after RotJ, Luke Skywalker started a Jedi Academy on the moon, and Exar Kun's power grew slowly until he was eventually destroyed by the fledging Jedi. Yavin's presense in SWG has been confirmed by the developers.
Chance: 100%

Kashyyyk: Kashyyyk is the homeplanet of the Wookies. It is covered in a dense layer of trees so tall and large that nobody has been to the surface of the planet in recent history. The large Wroshyr trees' branches weave together and combine into one, creating the large platforms used to house Wookie cities. These branches and whatnot also create several distinct eco-systems, each layered on top of the other. It is rumored that monsters dwell on the lower levels. No wookies have even ventured down past the 3rd layer and returned alive.
Chance: 85%

Mon Calamari: The homeworld to a species of the same-name, as well as the squid-headed Quarren, is covered in vast oceans. Almost no land exists at all. The Mon Calamari like is huge, floating cities. The real draw to Mon Calamari is the amazing ocean life, coral reefs, and exotic dangers. The famous Rebel leader, Admiral Ackbar, is from Mon Calamari. Mon Calamari is also known for it's immense knowledge bank of giant and ancient scallops.
Chance: 75%

Bespin: Bespin is a gas giant in a star system of the same name. It's many valuable gasses are harvested by it's settlers and sold to the rest of the galaxy to fuel starfighters and generators. Lando Calrissian ran an outpost on Bespin known as Cloud City until it was taken over by the Empire during the events of The Empire Strikes Back.
Chance: 70%

Nar Shaddaa: This Smuggler's Haven is the sole moon of the Hutt capital of Nal Hutta. It is home to every type of illegal operation you could possibly think of. Much of the moon is covered in huge buildings, making the entire surface look as if it's comprised of one giant city. Han Solo, Landa Calrissian, and many other smugglers spent a considerable amount of time on Nar Shaddaa before the events of Episode IV.
Chance: 69%

Bothawui: Bothawui is the homeworld of the Bothan Race. It is also one of the most important economical crossroads in the Galaxy. The New Republic Counselor Borsk Fey'lya hails from Bothawui.
Chance: 65%

Dagobah: Dagobah is a swamp planet teeming with life. It was the hiding place of the Jedi Master Yoda, and therefore the location where Luke Skywalker was trained in the Jedi ways. A few dozen years before Luke arrived on Dagobah, it was the location a tremendous force battle between Yoda and a Dark Jedi from Bpfassh.
Chance: 55%

Ryloth: Ryloth is planet the Twi'lek race calls home. It is rocky and barren on the surface, with vicious sand storms and other nasty weather. The Twi'leks live in underground caves.
Chance: 45%

Kessel: Kessel is a planetoid rich with spice, the Star Wars equivalent of drugs. The most popular type of spice on Kessel is glitterstim, which is mined in complete darkness in the tunnels beneath the various bases and startports on the rocky surface of the planetoid. Since Kessel is erratically shaped, it does not hold a breathable atmosphere, and thusly breathable air must be generated and unleashed onto the surface. This is accomplished by a number of 'atmosphere factories,' which create atmosphere and spit it into Kessel's stale air. Kessel is located in a system very near to one of the wonders of the Galaxy, the Maw. The Maw is a cluster of blackholes so close together then trying to skirt through them is nearly impossible. It is said that in the center of the great cluster there is a pocket of space where all of the gravitational phenomenon cancel out, but nobody has ever found a safe route in and survived [Read The Jedi Academy Series for more info on the Maw]
Chance: 40%

Honoghr: Honoghr is the homeworld of the species called Noghri. During the clone wars, a space battle erupted over the world and a debris from the battle fell upon the world, causing widespread destruction and rendering much of the world inhabitable. Years later, the Emperor found the world and tricked the Noghri into serving him in exchange for 'fixing' their planet. In reality he was spreading a poison that would leave the Noghri as his servants for eternity. Leia Organa Solo eventually discovered their plight and rescued the Noghri from servitude.
Chance: 35%

Nal Hutta: Nal Hutta is the "homeworld" of the Hutts. In reality, it is actually the second or third world they have called home. The worlds they live on get so polluted that they are forced to move their entire culture. Nal Hutta means 'Glorious Jewel' in Huttese, but you wouldn't know it by looking at the planet. Murky swamps and lakes cover the planet, giving it a distinct brownish colour.
Chance: 35%

Myrkr: Myrkr is a world long avoided by the Jedi types. One of it's native creatures, the yslarmiri, creates a bubble that pushes the force back, much like a balloon. For this reason, many smugglers set up bases on the world during the height of the Old Republic, hoping to avoid the "meddling Jedi." After the Jedi were exterminated, many of them left the world to set up on planets closer to their business. Talon Karrde, a smuggler, stayed on Myrkr after the mass exodus, and eventually captured Luke Skywalker and held him captive, helpless due to his lack of Force Powers on the world, for a short time.
Chance: 25%

Derra IV: Derra IV was the site of a successful assault by the empire on a Rebel convoy between the events of Star Wars Episodes 4 and 5.
Chance: 15%

Ithor: Ithor is a forested world populated by the native Ithorians, sometimes referred to as Hammerheads. The Ithorians think very highly of their forests, and thus do not even allow themselves to set foot on their Mother Nature's soil. Ithorians live in giant domed floating cities, which move silently over the forests without harming them. Ithor is said to be very beautiful - a great place to take a date. Wink wink. Nudge nudge.
Chance: 15%

Sullust: Sullust is the home planet of a species called the Sullustians. The surface of the planet is rocky and barren, so the Sullustians live in underground caves. Nien Nubb, Landa's copilot in the attack on the second Death Star, was a Sullustian from Sullust.
Chance: 15%

Selonia: Selonia is an ocean world, and one of the five planets in the Corellian system. It has the largest oceans of all the planets in the system. The planet is home to a poetic species of tall, sleek beings called the Selonians.
Chance: 10%

Tralus: Tralus and it's twin planet, Talus, orbit the ancient Centerpoint station in the Corellian system.
Chance: 10%

Bimmisaari: Bimmisaari is the homeworld of the Bimms. It is a temperate planet with a unique feature of trees that sway, as if in a breeze, even when there is no wind. It was the site of an attack on Leia Organa, Han Solo, and Luke Skywalker during the early days of the Thrawn campaign.
Chance: 5%

Dantooine: Dantooine is a remote, temperate world. It was used as a decoy by Princess Leia onboard the first Death Star before it shot and utterly destroyed Alderaan. Dantooine was also used as the resettlement for refugees from a volcanic planet that Luke Skywalker discovered in his search for Jedi Students. The settlement was destroyed shortly after it was built by the renegade Admiral Daala.
Chance: 5%

Duro: Duro is the homeworld of the Duros race. Until the emergence of the Empire, it was a attractive world with w temperate climate, but now it is used as a Toxic Waste dump by the Empire.
Chance: 5%

Drall: Drall is one of the five planets in the Corellia system. It is home to a species of the same name.
Chance: 5%

Nkllon: Nkllon is a planet extremely close to the sun in the Athega system. Harsh sunlight makes travelling to and from the planet nearly impossible - the intense heat fries sensors and hulls alike in minutes. However, on the bright side (haha.. pun!), the planet is extremely rich in all sorts of metals. Landa Calrissian set up a walking city on the dark side of the planet in order to mine it's precious metals sometime after RotJ.
Chance: 5%

Ord Mantell: Ord Mantell is the planet where Han Solo met up with two bounty hunters shortly before the events of The Empire Strikes Back.
Chance: 5%

Sluis Van: Home of some New Republic controlled shipyards. Guarded by some very nasty laser bearing space stations and a good 3 or 4 dozen capital ships at any one time. A planet best avoided if you work for the Empire, unless you bring Grand Admiral Thrawn along.
Chance: 5%

Toprawa: Toprawa was the planet that housed the team that stole the first Death Star plans until they could be beamed to Leia Organa's ship. As a result of this, their planet was ravaged by the Empire, and it's people reduced to almost animal standards of living.
Chance: 5%

Abregado-Rae: Abregado-Rae was a sleazy spaceport planet, almost as bad as the fabled Mos Eisley, during the height of the Empire. Since that time the local officials have cleaned up their act, and the cities are now much cleaner and more respectable.
Chance: 1%

Ammuud: Ammuud is a planet in the Corporate Sector.
Chance: 1%

Berchest: Berchest was a planet on the border between the Empire and the New Republic during Grand Admiral Thrawn's campaign. Thrawn routed clones through it as a diversion for whoever was trying to trace them back to their source. Some of Berchest's cities are hand-crafted from single, giant crystals.
Chance: 1%

Bomdan: Bomdan is a heavily industrialized planet in the Corporate Sector.
Chance: 1%

Bpfassh: Bpfassh was one of the three diversion attacks by Grand Admiral Thrawn before his main attack on Sluis Van about five years after Return of the Jedi. It was also home to a number of Dark Jedi a few dozen years before Episode IV. The Dark Jedi caused alot of damage to the world, and therefore the Bpfasshi have not trusted Jedi ever since.
Chance: 1%

Brigia: Brigia is a poor, backwater planet in the Tion Hegemony, a section of the Expansion Region of the Old Republic.
Chance: 1%

Chad: Chad is the home planet of the Chandra-Fan in a star system of the same name.

Chance: 1%

Deneba: Deneba is a desert world that figures prominently into Jedi history.
Chance: 1%

Duroon: Duroon is a volcanic world in the Corporate Sector.
Chance: 1%

Gamorr: Gamorr is the homeworld of the Gammorians. It's a nice place, too, or so I hear. The Gammorians tend to kill visitors.
Chance: 1%

Hoth: Hoth is the sixth planet in a system of the same name. It is covered in snow and freezing climates. The Rebel Alliance established a base on the planet in the same timeframe that Star Wars Galaxies is set in. Taun Tauns and Wampas are some of the creatures native to Hoth. The devs have stated there is little chance Hoth will make it into SWG, but I'm not giving up hope.
Chance: 1%

Jomark: Jomark was the planet on which the insane Jedi Joruus C'baoth set a "trap" for Luke Skywalker. C'baoth and his Imperial friends lured the young Jedi Knight to Jomark and then tried to twist him to the dark side.
Chance: 1%

Obra-Skai: Obra-Skai is the location of a massive library and data center in the New Republic. It is the site of an Imperial raid by Grand Admiral Thrawn during his short reign.
Chance: 1%

Thyferra: Thyferra is the planet in the Galactic Core that supplies the galaxy with most of it's Bacta.
Chance: 1%

Trogen: Trogen is the location of Whistler's Whirlpool, a failed restaurant/cantina that Talon Karrde used as a spot for some of his meetings in the early days of the Smuggler's Alliance.
Chance: 1%

Ukio: Ukio is one of the largest food producing planets in the galaxy.
Chance: 1%

Wayland: The planet Wayland houses the Emperor's "toy chest." Hidden within a mountain, this cache contains datacards, technology, and anything else that tickled the Emperor's funny-bone. The Planet is home to two native species, and some human settlers that crashed their transport on the world many years ago.
Chance: 1%

Z'trop: Z'trop is a beautiful and romantic volcano world. Apparently.
Chance: 1%

Alderaan: Alderaan is (was) a temperate planet 'close-ish' [new word!] to the Galactic Core. It's people were pacifists, choosing to fight with words rather then weapons. Alderaan was destroyed by the Empire during the events of Star Wars: A New Hope, and therefore has no chance of making it into Star Wars Galaxies, except as a field of rubble floating in space. Princess Leia Organa grew up on Alderaan.
Chance: 0%

Coruscant: Coruscant is widely viewed as the center of the political galaxy. Situated in the Galactic Core, the planet has been home to the current Government of the Galaxy, through the dark times of the Empire as well, since the dawn of the Old Republic. During Star Wars Galaxies, Coruscant is home to the Galactic Empire, as well as a number of criminal organizations, such as the infamous Black Sun. Much like Nar Shaddaa, but on a much larger scale, Coruscant is completely covered in cityscape, except for small areas near the poles. Coruscant is so utterly overpopulated that it could not sustain itself for more then a week on it's own, and therefore a large percentage of the food and supplies consumed by it's inhabitants is imported from other worlds. The developer's have confirmed that Coruscant is too complex and detailed to include in the initial release.
Chance: 0%
