The 80th parallel north is a circle of latitude that is 80 degrees north of the Earth's equatorial plane, and 10 degrees (690 miles / 1100 kilometers) south of the North Pole, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America. At this latitude the sun is visible for 24 hours, 0 minutes during the summer solstice and astronomical twilight during the winter solstice. (Wikipedia).
