Planet of Hoth
"here isn't enough life on this ice cube to fill a space cruiser."
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 plains. 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 omnivorous tauntauns, the herbivorous Hoth hogs, a few rodent species, including snowmice and ice scrabblers, and 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 -60ºC.
