1. Arctic Circle

   The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the Sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the Sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the Sun does not rise above the horizon for 40 successive days in midwinter.The position of the Arctic Circle is not fixed and currently runs 66°33′49.4″ north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, owing to tidal forces resulting from the orbit of the Moon. Consequently, the Arctic Circle is currently drifting northwards at a speed of about 14.5 m (48 ft) per year.

1. arctic circle

   The Arctic Circle is one of the five major circles of latitude on Earth's map. It is the parallel of latitude that runs approximately 66.34 degrees north of the Equator, marking the southern limit of the area where the sun does not rise on the winter solstice or set on the summer solstice - a phenomenon known as the polar night and midnight sun. The region north of this circle is known as the Arctic, which includes parts of Canada, Greenland, Finland, Norway, Sweden, Russia, the United States (Alaska), and Iceland.

1. Arctic Circle

   The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth. In 2012, it is the parallel of latitude that runs 66° 33′ 44″ north of the Equator. The region north of this circle is known as the Arctic, and the zone just to the south is called the Northern Temperate Zone. The equivalent polar circle in the Southern Hemisphere is called the Antarctic Circle. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours. North of the Arctic Circle, the sun is above the horizon for 24 continuous hours at least once per year and below the horizon for 24 continuous hours at least once per year. On the Arctic Circle those events occur, in principle, exactly once per year, at the June and December solstices, respectively. It would therefore seem that the Arctic Circle marks the southern extremity of the northern hemisphere polar day and polar night. In fact, because of atmospheric refraction and mirages, and because the sun appears as a disk and not a point, part of the midnight sun may be seen on the night of the northern summer solstice up to about 50′ south of the Arctic Circle; similarly, on the day of the northern winter solstice, part of the sun may be seen up to about 50′ north of the Arctic Circle. That is true at sea level; those limits increase with elevation above sea level although in mountainous regions, there is often no direct view of the true horizon.
