Extraterrestrial Polar Regions
Other planets and natural satellites in the solar system have interesting quirks about their polar regions. Earth's Moon is thought to contain substantial deposits of ice in deep craters in its polar regions, which never see direct sunlight. Mars, like Earth, has polar ice caps. On Uranus, meanwhile, the extreme tilt of the planet's axis leads to the poles alternately pointing almost directly at the Sun.
