The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is, subject to the caveats explained below, defined as the point in the northern hemisphere where the Earth's Earth is the third planet from the Sun. It is the fifth largest of the eight planets in the solar system, and the largest of the terrestrial planets in the Solar System in terms of diameter, mass and density. It is also referred to as the World, the Blue Planet,[note 3] and Terra.[note 4] axis of rotation meets the Earth's surface. It should not be confused with the North Magnetic Pole The Earth's North Magnetic Pole is the point on the Earth's surface at which the Earth's magnetic field points vertically downwards . This point moves gradually with time. As described later in this article, the North Magnetic Pole is physically a magnetic field south pole. The North Magnetic Pole should not be confused with the lesser known North.
The North Pole is the northernmost point on Earth, lying diametrically opposite the South Pole The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects the surface. It is the southernmost point on the surface of the Earth and lies on the opposite side of the Earth from the North Pole. Situated on the continent of Antarctica, it is the site of. It defines geodetic latitude 90° North, as well as the direction of True North True north usually differs from magnetic north and grid north (the direction northwards along the grid lines of a map projection). At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value.
While the South Pole lies on a continental land mass Antarctica (pronounced /ænˈtɑrktɪkə/ , is Earth's southernmost continent, underlying the South Pole. It is situated in the Antarctic region of the southern hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14.0 million km² (5.4 million sq mi), it is the fifth-largest continent in area, the North Pole is located in the middle of the Arctic Ocean The Arctic Ocean, located in the Northern Hemisphere and mostly in the Arctic north polar region, is the smallest, and shallowest of the world's five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying amidst waters that are almost permanently covered with constantly shifting sea ice. This makes it impractical to construct a permanent station at the North Pole (unlike the South Pole The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects the surface. It is the southernmost point on the surface of the Earth and lies on the opposite side of the Earth from the North Pole. Situated on the continent of Antarctica, it is the site of). However, the Soviet Union The Union of Soviet Socialist Republics was a constitutionally socialist state that existed in Eurasia from 1922 to 1991. The name is a translation of the Russian: Союз Советских Социалистических Республик (help·info), tr. Soyuz Sovetskikh Sotsialisticheskikh Respublik, abbreviated СССР, SSSR. The, and later Russia Russia (pronounced /ˈrʌʃə/ ; Russian: Россия transliterated: Rossiya , pronounced [rʌˈsʲijə]), officially known as both Russia and the Russian Federation (Russian: Российская Федерация (help·info), Rossiyskaya Federatsiya), is a country in northern Eurasia (Europe and Asia together). It is a semi-presidential, have constructed a number of manned drifting stations Soviet and Russian manned drifting ice stations are important contributors to exploration of the Arctic. An idea to use the drift ice for the exploration of nature in the high latitudes of the Arctic Ocean belongs to Fridtjof Nansen, who fulfilled it on Fram between 1893 and 1896. The first stations to use drift ice as means of scientific, some of which have passed over or very close to the Pole. Recently, scientists have predicted that the North Pole may become seasonally ice-free by 2065 due to Arctic shrinkage Arctic shrinkage is the decrease in size of the Arctic region (as defined by the 10 °C July isotherm). This is a change in the regional climate as a result of global warming. Recent projections of sea ice loss suggest that the Arctic ocean will likely be free of summer sea ice sometime between 2059 and 2078. Because of the rapid response of the.[1] More pessimistically, it was claimed by some scientists that the Arctic ice-cap might temporarily disappear in mid 2008, a prediction which did not come to pass.[2][3] On December 15, 2008, the Canadian science TV series Daily Planet reported that scientists now predict the ice cap could melt away by 2014.[4]
The sea depth at the North Pole has been measured at 4,261 metres (13,980 ft).[5] The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about 700 km (440 mi) away, though some perhaps non-permanent gravel banks lie slightly further north.

Q. Polaris is currently earth's "pole star." At some point in the distant past, there was a pole shift of earth's magnetic north pole. Before that shift, Vega was earth's pole star. How long ago did that pole shift occur?

A. First of all, it was not a "magnetic" pole shift -- it was a geographic pole shift. Second, it was not a "shift" -- it was a normal part of the slow precession of the the pole. It takes about 26,500 years for the pole to trace a circle in the sky. 13,000 years ago, the pole was pointed close to Vega. The precession is a slow steady movement, not a sudden "shift".
