North Pole
The point on the Earth's surface some 750 km north of Greenland through which passes the Earth's axis of rotation. It does coincide with the Earth's North Magnetic Pole, which is over 1,000 km away. The Pole lies roughly at the center of the Arctic Ocean, which there is permanently ice-covered, and experiences days and nights each of six months. It was first reached by Robert Peary on April 6, 1909. See also celestial sphere.
