Gethen

Gethen is the fictional planet where the action develops in the science fiction novel "The Left Hand of Darkness", by Ursula K. Le Guin.

Gethen appears to have a surface gravity more or less similar to Earth and a human-compatible atmosphere (the Earth envoy sent there shows no sign of discomfort).

Gethen's axis is not tilted (as is the case with Earth), but a relatively high orbital eccentricity produces global seasons. At the time of the story, Gethen is in the midst of an Ice Age (some local scientists believe it is near the end). The poles and a large portion of the land around them are permanently covered with glaciers, and even in the inhabited areas the climate can be extremely cold. In some places it is impossible to travel in winter, since the snow covers all roads. A summer day at 30 degrees Celsius is compared (by a Gethenian) to being inside a furnace.

Gethenians are physically and culturally adapted to cold; they tend to be of robust build and short stature, and they are familiar with the caloric yield of many different types of food. (The physical adaptations might be a product of genetic manipulation by the Hain, the species that "seeded" many worlds in the Ekumen with humanoid lifeforms.)
