The polar regions are constantly below 90°K (-183°C).

It is radically different from Earth in other respects.

It has been considered sacred by members of many civilizations, and has been a huge inspiration for poets, calling it the "autumn deity".

The two polar ice caps appear to be made largely of methane ice.
