Hoth was the sixth planet of the remote Hoth system and was desolate, ice-bound, and located in a rarely-visited sector of the Galaxy. It became famous as the one-time location of a Rebel Alliance base during the Galactic Civil War, and of the major battle there between Imperial and Rebel forces.
Located on the fringe of the Ivax Nebula in the Anoat Sector of the Greater Javin, along the Ison Corridor, Hoth orbited the blue-white star Hoth on a wide elliptical orbit. Beyond Hoth was a large asteroid belt, known as the Hoth Asteroid Field, from which small asteroids regularly broke off, crashing onto Hoth's surface as meteorites.
The planet consisted of a molten metallic core with dichotomous crust. Its surface was entirely covered by a frozen ocean, except where volcanic fissures opened up steam vents, depositing rock and minerals in darker patches on the glacier planes. A few mountain ranges pierced the permanent ice shelves, some being geologically active. The tidal pull of Hoth's three nameless moons caused fissures in the ice-layers, sending jets of ocean water into the freezing Hoth air. The intense cold froze these jets into spires of ice, suspending primitive ocean algae within these tall columns and glaciers. Massive oceanic currents beneath the southern hemisphere caused regular seismic activity, resulting in a constantly shifting landscape of caves and tunnels. Buried deep in Hoth's equatorial region was a fissure, reaching hundreds of meters towards the core of the planet. In this area never exposed to Hoth's blue-white sun was a cache of lumni-spice, a rare fungal growth.
Its orbit and axial tilt resulted in consistently icy weather patterns. Daytime temperatures reached levels unbearable to most species and rarely rose above freezing, even in the planet's relatively mild equatorial regions. The gale force winds and intense snowstorms that regularly wracked the windswept surface magnified the extreme cold of Hoth.
The frigid biosphere included a minimal food chain: the predator wampas, the omnivore tauntauns, Hoth hogs, a few rodent species, iceworms, lichens, and Dragon Slugs.
The average planetary temperature was around -61ºC; however at Echo Base, located near the planet's equator in the northern hemisphere, daytime temperatures could reach -32ºC; however night-time temperatures got as low as -60
Wampa ice creatures were carnivorous predatory reptomammals indigenous to the planet Hoth. Covered with white fur and averaging over two meters in height, their long arms ended in sharp claws that were strong enough to carve layers out of ice. Wampas rarely killed their prey outright or hunt when they were hungry. Instead, they stunned their prey, hauled the still breathing victims back to their caves, and secured them in the ice for later consumption. Their primary prey were tauntauns.
