10 Things You Never Knew About the Star Wars Galaxy

Little-known facts that even hardcore Star Wars fans have never heard.

What is Jabba the Hutt's last name? What world does Obi-Wan Kenobi hail from? How high do Coruscant's buildings and structures reach into the sky?

You may consider yourself something of a Star Wars buff, but I guarantee there are many, many things you don't know about all those characters, worlds, aliens and vehicles. Fortunately, you can find a ton of those facts inside the utterly fascinating book, Star Wars: Absolutely Everything You Need To Know.

Written by Adam Bray, Kerrie Dougherty, Cole Horton, and Michael Kogge, this over-sized hardcover packages Star Wars details in an infographic-style format that's easy on the eyes and fun to read.

Here are just ten things I learned from the book, but they barely scratch the surface of all that's inside.

Obi-Wan Kenobi's homeworld

It's never been seen on film or television -- or even spoken about by the character himself -- but Obi-Wan Kenobi's homeworld is called Stewjon.

George Lucas himself named the planet in honor of The Daily Show's former host, John Stewart.

Coruscant is really, really tall

You probably know that city-planet Coruscant has built levels atop levels for a very long time, like a building constructed around an entire world. You may even know that, as an episode of Star Wars: The Clone Wars revealed, it goes as far down as 1,300 levels, where the planet's criminal underworld exists.

But I bet you never knew this. According to Absolutely Everything You Need To Know, Coruscant's levels from its land mass base to the tippy-top of the highest building is 5,217! That's mind-boggling.

(Side note: shouldn't it be hard to breathe on the uppermost levels?)

The Death Star's superlaser is a ginormous lightsaber

Lightsabers require Kyber crystals in order to work. These powerful crystals are uniquely attuned to the Force, and come in a variety of colors that determine the color of the saber's blade. In a story arc of The Clone Wars, Padawans were taken to the planet Ilum to harvest Kyber crystals that they then used to make their lightsabers.

Have you ever thought about how much the green laser emitted by the Death Star looks kind of like a lightsaber beam? Turns out, the superlaser weapon in both Death Stars was "powered by hypermatter reactors," which "focused multiple lasers through massive Kyber crystals."

Leave it to Palpatine to find a way to corrupt something the Jedi consider precious.

Jabba's last name is not "the Hutt"

Jabba the Hutt. You hardly ever hear "Jabba" without "the Hutt," but it's pretty obvious that "the Hutt" isn't part of his name. It's what his species is called, after all.

But did you know Jabba has an actual last name?

It's never said in the films, but his full name is Jabba Desilijic. He's also a bigger deal than you probably thought. Not only is he head of the Desilijic crime family, he's the leader of his people's government, the Hutt Council.

Princess Leia assassinated the Hutt president. Who knew?

Stormtroopers have to give up their names

Being a Stormtrooper is hard. You have to put up with endless jokes about your marksmanship (or lack thereof). You get blown up by those pesky Rebels. You have to wear headgear that you can barely see out of.

But that pales next to the fact that when they graduate from the Imperial Academy, Stormtroopers must effectively give up their real names. For good.

Unlike Clone Troopers, who are assigned identification numbers at birth but tend to take on nicknames when they reach maturity, Stormtroopers set aside their real names and become known only by their identification numbers.

Sucks to be them.

Which is bigger: the Millennium Falcon or the Ghost?

The Millennium Falcon and Ghost (from Star Wars Rebels) are both Corellian model starships, with notable design similarities. The level of detail seen on the Falcon makes it look much bigger than the simpler, smoother look of the Ghost.

But the Ghost is actually bigger. Placed atop one another, the Ghost stretches out about thirty feet wider and deeper than the Falcon.

Its added size may account for why the Ghost is the slower of the two. The Ghost tops out at 636 miles per hour, while the Millennium can reach 652 miles per hour.

Speaking of speed...

The Rebellion has the fastest ship there is

Despite the boasts of Han Solo, the Millennium Falcon is not the fastest ship in the galaxy. Not by a long shot. A number of other models are easily able to best its speed, such as the X-Wing, Jedi Interceptor and TIE Fighter.

But the starship that flies the fastest is one of the smallest, and most likely to be ignored. It's the Rebel Alliance's standard A-Wing, the dependable little starfighter seen throughout multiple space battles in the original trilogy. It's probably best known as "that ship that crashed into the Star Destroyer's bridge in Return of the Jedi."

The A-Wing can reach speeds as high as 808 miles per hour.

The two Death Stars were more different than you think

Following the time-honored tradition of "if it doesn't work, make it bigger," the second Death Star featured a number of upgrades to the original design, not the least of which was its size.

The original Death Star was 75 miles in diameter, but the new-and-improved version was 99 miles in diameter. It boasted twice the number of turbolaser batteries, and nearly twice as many crew members.

But its biggest and best advancement was how fast its primary weapon, the superlaser, could be recharged. The first Death Star had a superlaser that required twenty-four hours to recharge after a single blast. The second could fire again after recharging for just three minutes.

Three brains walk into a starship...

Remember the scene in Empire Strikes Back where Han Solo needed C-3PO to "talk to the Falcon"? Han wasn't speaking metaphorically.

As everybody knows, Han and Chewie made a number of "special modifications" to the Millennium Falcon over the years. One of them was to upgrade the Falcon's main computer. And you'll never guess what they used.

The Falcon's computer is made of the mechanical brains of three droids. According to Absolutely Everything You Need to Know..., the brains used to belong to an R3 astromech droid, a V-5 transport droid, and a slicer droid. (Admit it: you feel kinda bad for those lobotomized droids.)

No wonder C-3PO was the only one that could talk to it.

Palpatine's Imperial Palace used to go by a different name

Although Coruscant was never seen in the original trilogy (aside from a brief glimpse added to Return of the Jedi's special edition), it was still there, and it was where Emperor Palpatine, aka Darth Sidious, lived for most of that time period.

Specifically, he lived in the lavish Imperial Palace, which of course was located on Coruscant. But before it was the Imperial Palace, it was something else -- something very different.

In the hundreds of years before the Empire was formed, the building that would be converted into the Imperial Palace was the Jedi Temple. In an act of spite that was as symbolic as it was practical, Palpatine desecrated the memory of the Jedi by turning their sacred temple into his personal bachelor pad.

Palpatine was just pure evil. But hey, at least he recognized the wisdom in recycling.
