In the 1980 film The Empire Strikes Back, Hoth is the home of the Rebel Alliance's secret Echo Base, which is partially installed in natural caves formed by giant ice bubbles. The Rebels patrol the planet by riding indigenous tauntauns. At the start of the film, Luke Skywalker and his tauntaun are attacked by a wampa. Skywalker eventually escapes and is rescued by Han Solo. When one of the Galactic Empire's probe droids uncovers the base, the Rebels are forced to evacuate. The Empire arrives and deploys ground forces to destroy the base, but the Rebels battle the AT-ATs with ground artillery and snowspeeders to stall them and effectively evacuate. This conflict is commonly referred to as the "Battle of Hoth". The original draft of The Empire Strikes Back, written by Leigh Brackett, depicted an opening scene with Luke Skywalker on the ridge of an ice planet, though the name "Hoth" was given to the cloud planet at the time. The draft also depicted Hoth's wampas attacking the Rebel base. The Hardangerjøkulen glacier near Finse, Norway, served as the filming location for Hoth in The Empire Strikes Back. Scenes were filmed in subzero temperatures. For the ground battle scene, miniatures were used on a set that used microscopic glass bubbles and baking soda to mimic the snowy territory.
''Legends''
Hoth has also appeared in Star Wars comics, books, and video games. In the 1983 Marvel Star Wars comic "Hoth Stuff!", it is revealed that Wedge Antilles went missing during the Battle of Hoth. In the novelDarksaber, Luke Skywalker and his lover Callista Ming travel to Hoth, where they encounter the same wampa that attacked Luke in Empire, but he swiftly kills it. In Shadows of the Empire, Hoth is one of several settings for Dash Rendar's adventures, including the Battle of Hoth.
Video games
The planet appears in ' during the first two story levels of Episode V and in the as multiplayer maps. It will also be a fully explorable hub world in the upcoming '.
Scientific accuracy
The planetary attributes of the fictional planet Hoth have been scrutinized for scientific accuracy. Space.com said Hoth most resembled the extrasolar planet OGLE-2006-BLG-390, "With a surface temperature of, it is nearly as frigid as Pluto." Bruce Betts of The Planetary Society said the asteroid belt near Hoth meant that the planet would have difficulty staying in place. With Hoth being bombarded frequently by asteroids, Betts said it would be unlikely for natural lifeforms to evolve on the planet. Jeanne Cavelos theorized in The Science of Star Wars that the frequency of meteoroids bombarding Hoth indicated that the planet was relatively young since in older solar systems, the debris is more cleared out. Since Hoth has complex lifeforms, Cavolos said the planet's age may be older, in the range of several billion years. The author said Hoth could be similar to Earth in age but lack neighboring planets like Jupiter and Saturn to shelter it from meteoroid impacts. She also said with the asteroid belt depicted in the film as close to Hoth that the belt was a likely source for meteoroids. CJ Miozzi, writing for The Escapist, said that Hoth was realistic as a single-biome planet, citing Jupiter's moon Europa as a similar example. Miozzi said the planet was depicted in the Star Wars books as being geologically active and having additional smaller lifeforms, including lichen. The author said lichen on Earth was an important part of the food chain during winter months but that it could grow back outside these months. With Hoth perpetually iced over, Miozzi said lichen likely would not be sufficient to support a multi-tiered food chain that includes an apex predator, the wampa.
