The area between the TROPICS and the North or South Pole of the earth. By subtracting 23?°27' - the position of the Tropic, from 90?° we get latitude of 66?°33'. These mark the Earth's Arctic or Antarctic circles (LESSER CIRCLES). At the Solstices, the Sun does not set in these regions but remains above the horizon for 24 hours.
