Antarctic Circle

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

The Antarctic Circle is one of the five major circles of latitude that mark maps of the Earth. It is the parallel of latitude 66? 33' 39" south of the equator (in 2000). For everywhere within the Antarctic Circle, there is at least twenty-four hours of continuous nighttime on the Summer Solstice, and at least twenty-four hours of continuous daytime on the Winter Solstice. This is because the earth is tilted at a 23.5 degree angle, and during the winter solstice, the northern hemisphere is tilted away from the Sun, meaning that the antarctic circle is completely tilted towards the Sun, hence it experiences 24 hour daylight, and vice versa. This time period increases as one aproaches the South Pole until at the South Pole there are six months of daylight during summer and six months of night during winter.
