The Arctic Circle is an imaginary line drawn around the northern part of the world at approximately 66° North. an imaginary line around the world at a particular distance from the most northern point, which is the North Pole Antarctic Circle. Parallel of latitude approximately
5° north of the Equator that circumscribes the northern frigid zone. It marks the southern limit of the area within which, for one day or more each year, the sun does not set or rise. The length of continuous day or night increases northward from the Arctic Circle, mounting to six months at the North Pole
a line of latitude near but south of the north pole; it marks the northernmost point at which the sun is visible on the northern winter solstice and the southernmost point at which the midnight sun can be seen on the northern summer solstice
The line of latitude 6634N (often taken as 66N) Along this line the sun does not set on the day of the summer solstice, about June 21, and does not rise on the day of the winter solstice, about December 22 From this line the number of twenty- four-hour periods of continuous day or of continuous night increases northward to about six months each at the North Pole

A line of latitude at 66° 33' North, when shown as a fixed position on a map, delineates a region, which at the time of the summer solstice (in the Northern Hemisphere), the Sun is above the horizon at local midnight time at all points in this region Also the complement of the Tropic of Cancer, which lies at latitude 23° 27' North
is a line of latitude at 66°33'N On the shortest day of the year, the center of the sun does not rise above the horizon at this latitude
