Polar circle
From Wikipedia, the free encyclopedia
A polar circle is either the Arctic Circle or the Antarctic Circle. On earth, the Arctic Circle is located at a latitude of 66˚ 33' 38" N, and the Antarctic circle is located at a latitude of 66˚ 33' 38" S. Areas between each polar circle and its associated pole (north pole, or south pole) will annually experience at least one 24 hour period when the sun is continuously above the horizon and at least one 24 hour period when the sun is continuously below the horizion.
