Polar region
From Wikinfo
A polar region is a large area found at the axis points that a planet spins around. The region is sometimes characterized by significantly lower temperatures than those found at an equator, which often leads to the formation of ice on planets which have surface water.
See: geographical pole, North Pole, South Pole.
