Latitude and longitude
- The northernmost point of Earth is the geographic North Pole, in the Arctic Ocean.
- The northernmost point on land is the northern tip of Kaffeklubben Island, north of Greenland ( ), which lies slightly north of Cape Morris Jesup, Greenland ( ). Various shifting gravel bars lie farther north, the most famous being Oodaaq. The northern most point of land is disputed.
- The southernmost point of the world and the southernmost point on land is the geographic South Pole, which is on the continent of Antarctica.
- The southernmost point off land is a bay on the Filchner-Ronne Ice Shelf at the coast of Antarctica ( ) about 100 km south of Berkner Island, the southernmost island of the world. The southern most point of Ocean is Gould Coast (84°30′S 150°0′WCoordinates: 84°30′S 150°0′W)
The southernmost open sea is also part of Ross Sea, namely Bay of Whales at 78°30'S, at the edge of Ross Ice Shelf. 1A 1995 realignment of the International Date Line () moved all of Kiribati to the Asian side of the Date Line, causing Caroline Island to be the easternmost. However, if the previous Date Line were followed, the easternmost point would be Tafahi Niuatoputapu, in the Tonga Islands chain.
- The westernmost and easternmost points of the world, based on the normal practice of using longitude, can be found anywhere along the 180th meridian in Siberia (including Wrangel Island), Antarctica, or the three islands of Fiji through which the 180th meridian passes (Vanua Levu's eastern peninsula, the middle of Taveuni, and the western part of Rabi Island).
- The westernmost point on land, according to the path of the International Date Line, is Attu Island, Alaska.
- The easternmost point on land, according to the path of the International Date Line, is Caroline Island, Kiribati1.
- The highest point measured from sea level is the summit of Mount Everest that borders Nepal and China, and was first reached by Sir Edmund Hillary of New Zealand and Sherpa of Nepal Tenzing Norgay (with speculation that it may have been reached in 1924). While measurements of its height vary slightly, the elevation of its peak is usually given as 8,848 m (29,029 feet) above sea level.
- The point farthest from the Earth's center is the summit of Chimborazo, in Ecuador, at 6,384.4 km (3,967 miles) (the peak's elevation in relation to the sea level is 6,268 m (20,564 feet)). This is due to the Earth being an oblate spheroid rather than a perfect sphere. An oblate spheroid is very much like a sphere except it is wider at the equator and narrower between the poles. This means that Chimborazo, which is near the equator, is farther away from the center of the Earth than the peak of Mount Everest. The summit of Mount Everest is 2.168 km (1.347 miles) closer at 6,382.3 km (3,965.8 miles) to the Earth's center. Peru's Huascarán contends closely with Chimborazo, the difference in the mountains' heights being 23 m (75 feet)
Lowest point (artificial)
- The lowest point underground ever reached was 12,262 m (40,230 feet) deep (SG-3 at Kola superdeep borehole).
- The lowest human-sized point underground is 3,900 m (12,800 feet) below ground at the TauTona Mine, Carletonville, South Africa.
- The lowest (from sea level) artificially made point with open sky might be the Hambach surface mine, Germany, 293 m (961 feet) below sea level.
- The lowest (from surface) artificially made point with open sky might be the Bingham Canyon open-pit mine, Salt Lake City, United States, 1,200 m (3,900 feet) below surface level.
- The lowest point underwater was the 10,680 m (35,040 feet)-deep (as measured from the subsea wellhead) oil and gas well drilled on the Tiber Oil Field located in the Gulf of Mexico. The wellhead of this well was an additional 1,259 m (4,131 feet) underwater for a total distance of 11,939 m (39,170 feet) as measured from sea level.
Lowest point (natural)
- The lowest known point is Challenger Deep, at the bottom of the Mariana Trench, 11,034 m (36,201 feet) below sea level. Only three humans have reached the bottom of the trench: Jacques Piccard and US Navy Lieutenant Don Walsh in 1960 aboard the bathyscaphe Trieste, and filmmaker James Cameron in 2012 aboard Deepsea Challenger.
- The lowest point underground is more than 2,000 m (6,600 feet) under the Earth's surface. For example, the altitude difference in the Krubera Cave between the entrance and the deepest explored point (its depth) is 2,191 ± 20 m (7,188 ± 66 feet). In 2012, Ukrainian cave diver Gennadiy Samokhin had reached the lowest point, breaking the world record.
- The lowest point on land not covered by liquid water is the valley under Byrd Glacier, which reaches 2,780 m (9,121 feet) below sea level. It is, however, covered by a thick layer of ice. See the extremes on Earth page. See list of places on land with elevations below sea level
- The lowest point on dry land is the shore of the Dead Sea, shared by Israel, the West Bank, and Jordan, 418 m (1,371 feet) below sea level. See List of places on land with elevations below sea level
- The point closest to the Earth's centre (~6,353 km (3,948 miles)) is the bottom of the Arctic Ocean (greatest depth 5,450 m (17,881 feet)) near the Geographic North Pole (the bottom of the Mariana Trench is near 6,370 km (3,958 miles) from the centre of the Earth).
Highest attainable by transportation

Outside tunnels, the lowest railway is 71 m (233 feet) below sea level, on the line connecting Yuma, Arizona, and Palm Springs, California, in the United States.
Highest geographical features
- Lake: There is an unnamed crater lake on Ojos del Salado (which itself is the world's highest volcano) at 6,390 m (20,965 feet), on the Argentina–Chile border (the lake is in Argentina). Another candidate is Lhagba Pool on the northeast slopes of Mount Everest, Tibet, China at an elevation of 6,368 m (20,892 feet).
- Navigable Lake: Lake Titicaca, on the border of Peru and Bolivia in the Andes, 3,812 m (12,507 feet)

- River: One candidate from among many possibilities is the Ating Ho (Ho meaning river), which flows into the Aong Tso (Hagung Tso), a large lake in Tibet, China, and is about 6,100 m (20,013 feet) at its source at . A very large high river is the Yarlung Tsangpo or upper Brahmaputra River in Tibet, China, whose main stem, the Maquan River has its source at about 6,020 m (19,751 feet) above sea level at . Above these elevations there are no rivers since the temperature is almost always below freezing.
- Island: There are a number of islands in the Orba Co lake, which is located at an elevation of 5,209 m (17,090 feet) in Tibet, China.
Each continent has its own Continental Pole of Inaccessibility, defined as the place on the continent that is farthest from any ocean. Of these continental points, the most distant from an ocean is the Eurasian Pole of Inaccessibility (or "EPIA") , in China's Xinjiang region near the Kazakhstan border. Calculations have commonly suggested that it is 2,645 km (1,644 miles) from the nearest coastline, located in the Dzoosotoyn Elisen Desert. The nearest settlement to the EPIA is Suluk at about 11 km (6.8 miles) to the east.
A recent study suggests that the historical calculation of the EPIA has failed to recognize the point where the Gulf of Ob joins the Arctic Ocean, and proposes instead that varying definitions of coastline could result in other Eurasian Pole of Inaccessibility results: EPIA1 somewhere between and , about 2510±10 km from the nearest ocean, or EPIA2 somewhere between and , about 2514±7 km from the nearest ocean. If adopted, this would place the final EPIA roughly 130 km (81 miles) closer to ocean than currently agreed upon.
Coincidentally, EPIA1 (or EPIA2) and the most remote of the Oceanic Poles of Inaccessibility (specifically, the point in the South Pacific Ocean that is farthest from land) are similarly remote; EPIA1 is less than 200 km (120 miles) closer to the ocean than the Oceanic Pole of Inaccessibility is to land.
- Other continents' poles of inaccessibility are as follows:
- Africa: , close to the tripoint of Central African Republic, South Sudan and Democratic Republic of the Congo, also close to Obo, Central African Republic
- Australia: either , or ., near Papunya, Northern Territory;
- North America: , between Kyle and Allen, South Dakota, United States;
- South America: , near Arenápolis, Mato Grosso, Brazil;
- The Pacific pole of inaccessibility (also called Point Nemo), the point in the ocean farthest from any land, lies in the South Pacific Ocean at , which is approximately 2,688 km (1,670 mi) from the nearest land (equidistant from Ducie Island in the Pitcairn Islands to the north, Maher Island off Siple Island near Marie Byrd Land, Antarctica, to the south and Motu Nui off Rapa Nui in the north east).
- The most remote island is Bouvet Island, an uninhabited and small Norwegian island in the South Atlantic Ocean. It lies at coordinates . The nearest land is the uninhabited Queen Maud Land, Antarctica, over 1,600 km (994 mi) away to the south. The nearest inhabited lands are Tristan da Cunha, 2,260 km (1,404 mi) away and South Africa, 2,580 km (1,603 mi) away.
- The most remote archipelago and the most remote inhabited island is Tristan da Cunha in the South Atlantic Ocean, 2,434 km (1,512 mi) from Saint Helena, 2,816 km (1,750 mi) from South Africa, and 3,360 km (2,090 miles) from South America. If Gough Island, which is 399 km (248 mi) away from the main island, is considered part of this archipelago, the nearest land from it should be Bouvet Island, 1,845 km (1,146 mi) away. The islands are part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha. With a population of approximately 270, the main island of Tristan da Cunha is also the remotest inhabited island in the world. Tristan da Cunha has no airport, so all travel must be by boat, making it the most remote inhabited place by transport time. Boat travel to the nearest scheduled airport in South Africa takes around five days.
- The most remote city
- The most remote city with a population in excess of one million, from another city of at least that population: Auckland, New Zealand. The nearest city of comparable size or greater is Sydney, Australia, 2,168.9 kilometres (1,347.7 mi) away. Coming in a close second at 2,139 kilometres (air travel distance) is Perth, Australia. Its nearest city of at least one million population is Adelaide, Australia.
- The most remote city with a population in excess of one million, from another city with population above 100,000: is Perth, Australia, located 2,138 km away from Adelaide, Australia. Auckland, New Zealand is a notable contender for this title with a distance of 2,155 km to Sydney – however, it is situated quite close to Hamilton, population 153,000, located 114 km (71 miles) away.
- The most remote city with a population in excess of 500,000, from another city of at least that population is Honolulu, United States. The nearest city of comparable size or greater is San Francisco, 3,841 km (2,387 miles) away.
- The most remote capital city in the world (longest distance from one capital of a sovereign country to the one closest to it) is a tie between Wellington, New Zealand, and Canberra, Australia, which are 2,326 km (1,445 mi) apart from each other. Canberra could drop from this tie in the future as it is only 2,217 km (1,378 mi) from Noumea, the capital of New Caledonia, a special territory of France which is scheduled to vote on independence between 2014 and 2018.
- The most remote airport in the world from another airport is Mataveri International Airport (IPC) on Easter Island, which has a single runway for military and public use. It is located 2,603 km (1,617 mi) from Totegegie Airport (GMR; very few flights) in the Gambier Islands, French Polynesia and 3,759 km (2,336 mi) from Santiago, Chile (SCL; a fairly large airport). In comparison, the airport at the Amundsen–Scott South Pole Station (NZSP) is not very remote at all, being located only 1,355 kilometres (842 mi) from Williams Field (NZWD) near Ross Island.
The world's farthest-apart city pairs (with a population of over 100,000) are:
- Rosario, Argentina to Xinghua, China - distance apart 19,996 km (12,425 mi).
- Liu'an, China to Río Cuarto, Argentina - distance apart 19,994 km (12,424 mi).
- Cuenca, Ecuador to Subang Jaya, Malaysia - distance apart 19,989 km (12,421 mi).
Since the Earth is a spheroid, its center (the core) is thousands of kilometres beneath its crust. On the surface, the point 0°, 0°, located in the Atlantic Ocean approximately 614 km (382 miles) south of Accra, Ghana, in the Gulf of Guinea, at the intersection of the Equator and Prime Meridian, at the coordinates of zero degrees by zero, is the "center" of the standard geographic model, as viewed on a map—but this selection of longitude meridian is culturally and historically dependent. The center of population, the place to which there is the shortest average route for everyone in the world, could be considered a centre of the world, and is located in the north of the Indian subcontinent, although the precise location has never been calculated and is constantly shifting.
