Extremes on Earth

Latitude and longitude

Northernmost

• The northernmost point of 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. There have been other islands more northern such as 83-42 and ATOW1996 but they have not been confirmed as permanent.

  Southernmost

• The southernmost continental point of land outside Antarctica is in South America at Cape Froward, Magallanes Region, Chile.
• The southernmost point of water is a bay on the Filchner–Ronne Ice Shelf along the coast of Antarctica, about south of Berkner Island.
• * The southernmost point of ocean is located on the Gould Coast.
• * The southernmost point of open ocean is in the Bay of Whales, also part of the Ross Sea, at 78°30'S, at the edge of the Ross Ice Shelf.
• ** The southernmost island is considered to be Deverall Island, near the Shackleton Coast, surrounded by the Ross Ice Shelf although there is an island in Lake Vostok but it is currently under ice.

  Easternmost and westernmost

• The easternmost and westernmost points on Earth, based on the east–west standard for describing longitude, can be found anywhere along the 180th meridian, which passes through the Arctic, Pacific, and Southern Oceans, as well as parts of Siberia, Antarctica, and three islands of Fiji.
• * Using instead the path of the International Date Line, i.e. define "easternmost" as "the first to see a new day" and define "westernmost" as "the last to see a new day", the westernmost point on land is Attu Island, Alaska, and the easternmost point on land is Caroline Island, Kiribati.

  Longest grid lines

Along constant latitude

• The longest continuous east–west distance on land is along the latitude 48°24'53"N, from the west coast of France through Central Europe, Ukraine, Russia, Kazakhstan, Mongolia and China, to a point on the east coast of Russia.
• The longest continuous east–west distance at sea is along the latitude 55°59'S, south of Cape Horn, South America.
• * The longest continuous east–west distance at sea between two continents is along the latitude 18°39'12"N, from the coast of Hainan, China across the Pacific Ocean to the coast of Michoacán, Mexico.

  Along constant longitude

• The longest continuous north–south distance on land is along the meridian 99°1'30"E, from the northern tip of Siberia in the Russian Federation, through Mongolia, China, and Myanmar, to a point on the south coast of Thailand.
• * The longest in Africa is along the meridian 20°12'E, from the north coast of Libya, through Chad, Central African Republic, Democratic Republic of the Congo, Angola, Namibia, and Botswana, to the south coast of South Africa.
• * The longest in South America is the length along the meridian 70°2'W, from the north coast of Venezuela, through Colombia, Ecuador, Peru, and Chile, to the southern tip of Argentina.
• * The longest in North America is along the meridian 97°52'30"W, from northern Canada, through the United States, to southern Mexico.
• The longest continuous north–south distance at sea is along the meridian 34°45'45"W, from the coast of Eastern Greenland across the Atlantic Ocean to the Filchner-Ronne Ice Shelf, on the coast of Antarctica. The longest in the Pacific Ocean is along the meridian 172°8'30"W, from the coast of Siberia to the Ross Ice Shelf in Antarctica.
• The meridian that crosses the greatest total distance on land is still to be determined. It is likely located in the vicinity of 22°E, which is the longest integer meridian that fits that criterion, crossing a total of of land through Europe, Africa, and Antarctica. More than 65% of this meridian's length is located on land. The next six longest integer meridians by total distance over land are, in order:
• * 23°E: through Europe, Africa, and Antarctica
• * 27°E: through Europe, Asia, Africa, and Antarctica
• * 25°E: through Europe, Africa, and Antarctica
• * 26°E: through Europe, Africa, and Antarctica
• * 24°E: through Europe, Africa, and Antarctica
• * 28°E: through Europe, Asia, and Africa

  Along any geodesic

• The longest continuous straight-line path over land is long and spans between the West African coast near Greenville, Liberia and a peninsula about northeast of Wenzhou, China, passing over the Suez Canal.
• * The longest continuous straight-line land distance solely within continental Africa is, along a line that begins just east of Tangier, Morocco, and ends east of Port Elizabeth, South Africa. This line passes through Morocco, Algeria, Mali, Niger, Nigeria, Cameroon, Equatorial Guinea, Gabon, Republic of the Congo, Democratic Republic of the Congo, Angola, Namibia, Botswana, and South Africa.
• * The longest continuous straight-line land distance solely within continental Asia is, along a line that begins on the Indian coast near Kanyakumari and ends at the Bering Sea coast of the Chukchi Peninsula in Russia. This line passes through India, Nepal, China, Mongolia, and Russia.
• * The longest continuous straight-line land distance solely within continental Europe is, along a line that begins at Cape St. Vincent, Portugal, and ends at the Urals, near the town of Perm, Russia. This line passes through Portugal, Spain, France, Germany, Poland, Lithuania, Belarus, and Russia.
• * The longest continuous straight-line land distance solely within continental North America is, along a line that begins at Point Hope, Alaska, United States, and ends southwest of the town of Salina Cruz, Mexico. This line passes through Alaska, Canada, the contiguous United States, and Mexico.
• * The longest continuous straight-line land distance solely within continental South America is, along a line that begins northeast of Puerto Cumarebo, Venezuela, and ends south of the town of Punta Arenas, Chile. This line passes through Venezuela, Colombia, Brazil, Peru, Chile, and Argentina.
• * The longest continuous straight-line land distance solely within continental Australia is, along a line that begins at the southern end of Cape Range National Park in Western Australia and ends at the town of Byron Bay in New South Wales.
• There are several possible candidates for the longest continuous straight-line distance in any direction at sea, as there are many possible ways to travel along a great circle for more than the antipodic length of. Some examples of such routes would be:
• * From the south coast of Balochistan province somewhere near Port of Karachi, Pakistan across the Arabian Sea, southwest through the Indian Ocean, near Comoros, passing Namaete Canyon, near the South African coast, across the South Atlantic Ocean, then west across Cape Horn, then northwest across the Pacific Ocean, near Easter Island, passing the antipodal point near Emlilia island, through the South Bering Sea and ending somewhere on the northeast coast of Kamchatka, near Ossora. This route is long. This route was confirmed to be the longest given map data at a level of resolution.
• * From the south coast of Hormozgan province, Iran across the Gulf of Oman, southeast across the Arabian Sea, passing south of Australia and New Zealand, near the Antarctic coast, then northeast across the South Pacific Ocean, passing the antipodal point and ending on the southwest coast of Mexico somewhere near Ciudad Lázaro Cárdenas. This route is long.
• * From Invercargill, New Zealand across Cape Horn, then off the coast of Brazil close to Recife, passing north of Cape Verde, passing the antipodal point and ending somewhere on the southwest coast of Ireland. This route is long.

  Along any diameter (straight line passing through the centre of the Earth)

Elevation

Highest points

• The highest point on Earth's surface measured from sea level is the summit of Mount Everest, on the border of Nepal and China. While measurements of its height vary slightly, the elevation of its peak was most recently established in 2020 by the Nepali and Chinese authorities as above sea level. The summit was first reached probably by Sir Edmund Hillary of New Zealand and Tenzing Norgay Sherpa of Nepal in 1953.
• The point farthest from Earth's centre is the summit of Chimborazo in Ecuador, at from Earth's centre; the peak's elevation relative to sea level is. Because Earth is an oblate spheroid rather than a perfect sphere, it is wider at the equator and narrower toward each pole. Therefore, the summit of Chimborazo, which is near the Equator, is farther away from Earth's centre than the summit of Mount Everest is; the latter is closer, at from Earth's centre. Peru's Huascarán contends closely with Chimborazo, though the former is a mere closer to the Earth's centre.
• The fastest point on Earth or, in other words, the point farthest from Earth's rotational axis is the summit of Cayambe in Ecuador, which rotates around Earth's axis at a speed of and is from the axis. Like Chimborazo, which is the fourth-fastest peak at, Cayambe is close to the Equator and takes advantage of the oblate spheroid figure of Earth. More important, however, Cayambe's proximity to the Equator means that the majority of its distance from the Earth's centre contributes to Cayambe's distance from the Earth's axis.

  Highest geographical features

• The highest volcano is Ojos del Salado on the Argentina–Chile border. It has the highest summit,, of any volcano on Earth.
• The highest natural lake is an unnamed crater lake on Ojos del Salado at, on the Argentina side. Another candidate was Lhagba Pool on the northeast slopes of Mount Everest, Tibet, at an elevation of, which has since dried up.
• The highest navigable lake is Lake Titicaca, on the border of Bolivia and Peru in the Andes, at.
• The highest glacier is the Khumbu Glacier on the southwest slopes of Mount Everest in Nepal, beginning on the west side of Lhotse at an elevation of.
• The highest river is disputed; one candidate from many possibilities is the Ating Ho, which flows into the Aong Tso, a large lake in Tibet, and has an elevation of about at its source at. Another very large and high river is the Yarlung Tsangpo or upper Brahmaputra River in Tibet, whose main stem, the Maquan River, has its source at about above sea level at. Above these elevations, there are no constantly flowing rivers since the temperature is almost always below freezing.
• The highest island is one of a number of islands in the Orba Co lake in Tibet, at an elevation of.

  Highest points attainable by transportation

• The highest point accessible
• *by land vehicle is an elevation of on Ojos del Salado in Chile, which was reached by the Chilean duo of Gonzalo and Eduardo Canales Moya on 21 April 2007 with a modified Suzuki Samurai, setting the high-altitude record for a four-wheeled vehicle.
• * by road is on a mining road to the summit of Aucanquilcha in Chile, which reaches an elevation of. It was once usable by 20-tonne mining trucks. The road is no longer usable.
• * by road is disputed; there are a number of competing claims for this title due to the definition of "motorable pass" :
• ** The highest asphalted road is the single-lane road to Umling La, located west of Demchok in Ladakh, India, which reaches . Before the asphalting of the road over Umling La, the highest asphalted road was Tibet's Semo La pass at. It is used by trucks and buses regularly. The Ticlio pass, on the Central Road of Peru, is the highest surfaced road in the Americas, at an elevation of.
• ** The highest unsurfaced road has several different claimants. All are unsurfaced or gravel roads including Mana Pass, between India and Tibet, which is crossed by a gravel road reaching. The heavily trafficked Khardung La in Ladakh lies at. A possibly motorable gravel road crosses Marsimik La in Ladakh at.
• * by train is Tanggula Pass, located on the Qinghai–Tibet Railway in the Tanggula Mountains of Qinghai/Tibet, China, at. The Tanggula railway station is the world's highest railway station at. Before the Qingzang Railway was built, the highest railway ran between Lima and Huancayo in Peru, reaching at Ticlio.
• * by oceangoing vessel is a segment of the Rhine–Main–Danube Canal between the Hilpoltstein and Bachhausen locks in Bavaria, Germany. The locks artificially raise the surface level of the water in the canal to above mean sea level, higher than any other lock system in the world, making it the highest point currently accessible by oceangoing commercial watercraft.

• The highest commercial airport is Daocheng Yading Airport, Sichuan, China, at. The proposed Nagqu Dagring Airport in Tibet, if built, will be higher at.
• The highest helipad is Sonam, Siachen Glacier, India, at a height of above sea level.
• The highest permanent human settlement is La Rinconada, Peru,, in the Peruvian Andes.
• The farthest road from the Earth's centre is the Road to Carrel Hut in the Ecuadorian Andes, at an elevation of above sea level and a distance of from the centre of the Earth.

  Lowest points

Lowest natural points

• The deepest point below the ocean's atmospheric surface is Challenger Deep, at the bottom of the Mariana Trench, below sea level. Jacques Piccard and U.S. Navy Lieutenant Don Walsh first reached Challenger Deep in 1960 aboard the bathyscaphe Trieste, followed by filmmaker James Cameron in 2012 aboard Deepsea Challenger. Between 2020 and 2022, DSV Limiting Factor made 19 dives to Challenger Deep, carrying with it 19 further visitors.
• The deepest known cave is in the Krubera Cave in Abkhazia, with its deepest known point 2,199 ± 20 metres below its entrance. The record was set in 2006, and it remains one of only two known caves deeper than 2,000 meters.
• The lowest point on land not covered by liquid water is the canyon under Denman Glacier in Antarctica, with the bedrock being below sea level.

• The lowest point on dry land is the shore of the Dead Sea, shared by Israel, Palestine and Jordan, below sea level. As the Dead Sea waters are receding, the water surface level drops more than per year.
• The point on the atmospheric surface closest to the Earth's centre is the surface of the Arctic Ocean at the Geographic North Pole.
• * The point on the surface of Earth's crust closest to the Earth's centre is the bottom of Litke Deep, in the Arctic Ocean, at from Earth's centre; the deep's depth relative to sea level is. Because Earth is an oblate spheroid rather than a perfect sphere, it is wider at the equator and narrower toward each pole. Therefore, the bottom of Litke Deep, which is near the North Pole, is closer to Earth's centre than the bottom of Challenger Deep is; the latter is further, at from Earth's centre. Molloy Deep, also in Arctic Ocean from Earth's centre contends closely with Litke Deep, the difference from Earth's centre being just.
• * The point on the ocean surface farthest below sea level is located in the Indian Ocean, about southwest of India, the Indian Ocean Geoid Low, about below the global mean sea level.

  Lowest artificial points

• The lowest point underground ever reached was deep.
• The lowest human-sized point underground is below ground at the TauTona Mine, Carletonville, South Africa.
• The lowest artificially made point with open sky may be the Hambach surface mine, Germany, which reaches a depth of below sea level.
• The lowest artificially made point with open sky may be the Bingham Canyon Open Pit Copper Mine, Utah, United States, at a depth of below surface level.
• The lowest point underwater is the -deep oil and gas well drilled on the Tiber Oil Field in the Gulf of Mexico. The wellhead of this well is an additional underwater, for a total distance of as measured from sea level.

  Lowest points attainable by transportation

• The lowest point accessible:
• * by road, excluding roads in mines, is any of the roads alongside the Dead Sea in Israel, Palestine and Jordan, which are the lowest on Earth at below sea level.
• ** The lowest undersea highway tunnel is the Ryfast tunnel in Norway, at below sea level.
• * by train, excluding tracks in mines, is located in the Seikan Tunnel in Japan, at below sea level. For comparison, the undersea Channel Tunnel between the UK and France reaches a depth of below sea level.
• * by ship, is located in the Indian Ocean, about southwest of India, the Indian Ocean Geoid Low, about below the global mean sea level.
• * Some mines have roads accessible from outside or rail tracks, located more than two thousand metres below sea level, for example in some South African gold mines.
• The lowest railroad station was formerly the Japanese Yoshioka-Kaitei Station, at below sea level, but it closed in 2014. The lowest railroad station not inside a tunnel is below sea level, at Beit She'an railway station in Israel.
• The lowest airfield is the Bar Yehuda Airfield, near Masada, Israel, at below sea level.
• The lowest international airport is Atyrau Airport, near Atyrau, Kazakhstan, at below sea level, in the basin of the Caspian Sea.
• The lowest major city is Baku, Azerbaijan, located below sea level, which makes it the lowest-lying national capital in the world and also the largest city in the world located below sea level.

Poles of inaccessibility

Continental

• The most distant point from an ocean is the Eurasian Pole of Inaccessibility , in China's Xinjiang region near the border with Kazakhstan. Calculations have shown that this point, located in the Dzoosotoyn Elisen Desert, is from the nearest coastline. The nearest settlement to the EPIA is Suluk at, about to the east. A 2007 study suggests that the historical calculation of the EPIA 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 locations for the EPIA:
• * EPIA1, somewhere between and, is about from the nearest ocean.
• * EPIA2, somewhere between and, is about from the nearest ocean.
• The continental poles of inaccessibility for the other continents are as follows:
• * Africa:, close to the tripoint of the Central African Republic, South Sudan, and the Democratic Republic of the Congo
• * Australia: either, or, near Papunya, Northern Territory
• * North America:, between Kyle, South Dakota and Allen, South Dakota, United States.
• * South America:, near Arenápolis, Mato Grosso, Brazil

  Oceanic

• The most distant point from land is the Pacific pole of inaccessibility, which lies in the South Pacific Ocean at, about from the nearest land. The centre of the Pacific Ocean and the Water Hemisphere lie west to it, closer to Oceania, off the coast of Kiribati at and New Zealand at respectively.

  Other places considered the most remote

• The most remote island is Bouvet Island, a small, uninhabited island in the South Atlantic Ocean that is a dependency of Norway. It lies at coordinates. The nearest land is the uninhabited Queen Maud Land, Antarctica, over to the south. The nearest inhabited lands are Gough Island, away, Tristan da Cunha, away, and the coast of South Africa, away.
• The title for most remote inhabited island or archipelago depends on how the question is interpreted. If the south Atlantic island Tristan da Cunha and its dependency Gough Island, which are from each other, are considered part of the same archipelago, or if Gough Island is not counted because it has no permanent residents, then Tristan da Cunha is the world's most remote inhabited island/archipelago: the main island, also called Tristan da Cunha, is from the island Saint Helena, from South Africa, and from South America. It is away from uninhabited Bouvet Island. However, if Gough and Tristan da Cunha are considered separately, they disqualify each other, and the most remote inhabited island is Easter Island in the South Pacific Ocean, which lies from Pitcairn Island, from Rikitea on the island of Mangareva, and from the coast of Chile. The Kerguelen Islands in the southern Indian Ocean are another contender, lying from the small Alfred Faure scientific station in Île de la Possession, but otherwise more than from the coast of Madagascar, northwest of the uninhabited Heard Island and McDonald Islands, and from the non-permanent scientific station located in Île Amsterdam.
• Remote cities
• * The most remote city with a population in excess of one million from the nearest city with a population in excess of one million is Auckland, New Zealand. The nearest city of comparable size or greater is Sydney, Australia, away.
• * The most remote city with a population in excess of one million from the nearest city with a population above 100,000 is Perth, Australia, located away from Adelaide, Australia.
• * The most remote city with a population in excess of 100,000 from the nearest city with a population in excess of 100,000 is Honolulu, Hawaii, United States. The nearest city of comparable size or greater is San Francisco, away.
• * The most remote national capitals are Wellington, New Zealand, and Canberra, Australia, which are apart from each other and neither is closer to another capital.
• The most remote airport in the world from another airport is Mataveri International Airport on Easter Island, which has a single runway for military and public use. It is located from Totegegie Airport in the Gambier Islands, French Polynesia and from Santiago, Chile. In comparison, the airport at the Amundsen–Scott South Pole Station is far less remote, being located only from Williams Field near Ross Island.

  Centre

• The centre of the standard geographic model as viewed on a traditional world map is the point 0°, 0°, which is located in the Atlantic Ocean about south of Accra, Ghana, in the Gulf of Guinea. It lies at the intersection of the Equator and the Prime Meridian, is marked with a buoy, and is sometimes called Null Island. However, the selection of the Prime Meridian as the 0° longitude meridian depended on cultural and historical factors and is therefore geographically arbitrary ; consequently, the position of the "Null Island" centrepoint is also arbitrary.
• The centre of population, the place to which there is the shortest average route for every individual human being in the world, could also be considered a "centre of the world". This point is located in the north of the Indian subcontinent, although the precise location has never been calculated and is constantly shifting due to changes in the distribution of the human population across the planet.
