Point Nemo: Distance from Land and People

Point Nemo, officially known as the Oceanic Pole of Inaccessibility, is the point in the ocean farthest from any land. The nearest land is about 2,688 kilometers (1,670 miles) away, and the nearest humans are typically the astronauts aboard the International Space Station, which orbits roughly 400 kilometers (250 miles) overhead. This article explains exactly how far Point Nemo is from land and people, how that distance is measured, and why this remote spot fascinates scientists and explorers.

What Is Point Nemo?

Point Nemo is the name given to the location in the South Pacific Ocean that is the farthest from any coastline. It was calculated in 1992 by Croatian survey engineer Hrvoje Lukatela, who used a computer program to find the point on the globe that maximizes the distance to the nearest land. The name comes from Jules Verne’s character Captain Nemo, not from the Disney clownfish, and it is also sometimes called the “pole of inaccessibility” for the Pacific Ocean.

The coordinates of Point Nemo are approximately 48°52.6′S 123°23.6′W. It lies in the South Pacific Gyre, a massive rotating ocean current that keeps nutrient-poor water and limits marine life. The nearest landmasses are:

• Ducie Island (part of the Pitcairn Islands) to the north
• Motu Nui (a small islet near Easter Island) to the northeast
• Maher Island (off the coast of Antarctica) to the south

These three points form a rough triangle, and Point Nemo is the center of that triangle, equidistant from all three.

How Far Is Point Nemo from Land?

The shortest distance from Point Nemo to any of those three landmasses is approximately 2,688 kilometers (1,670 miles). That is the distance to Ducie Island, Motu Nui, and Maher Island, all of which are about the same distance away. To put that in perspective:

• It is roughly the distance from New York City to Salt Lake City.
• It is about the same as flying from London to Cairo.
• It is more than 1,000 miles farther than the distance from Los Angeles to Honolulu.

Because the Earth is a sphere, the distance is measured along the great-circle path, which is the shortest route between two points on the surface. The calculation uses the Earth’s radius and the coordinates of the nearest land, and it accounts for the fact that land is not a single point but a coastline. The distance is the same to all three landmasses because Point Nemo is defined as the point where those distances are equal.

How Far Is Point Nemo from the Nearest People?

The nearest humans to Point Nemo are usually not on the ocean surface at all. They are astronauts aboard the International Space Station (ISS), which orbits at an altitude of about 400 kilometers (250 miles). When the ISS passes directly over Point Nemo, the astronauts are closer to that spot than any person on Earth. This happens regularly because the ISS orbits the Earth about every 90 minutes, and its ground track covers most of the planet, including the remote South Pacific.

If you are asking about people on the surface, the nearest are typically the crew of a passing ship, which is rare. The South Pacific Gyre is far from shipping lanes, and the area around Point Nemo is known for having almost no vessel traffic. Occasionally, research vessels or yachts on a round-the-world voyage pass nearby, but they are still hundreds of kilometers away. In practice, the nearest humans on Earth are likely on Easter Island (about 3,200 km away) or in New Zealand (about 4,800 km away), but those are not the closest points of land—they are just the closest inhabited places.

Why Is Point Nemo So Remote?

Point Nemo’s remoteness is a result of the distribution of continents and islands on Earth. The Pacific Ocean is the largest ocean, and its southern part has few islands. The nearest landmasses are small, uninhabited islands or parts of Antarctica, and they are all roughly the same distance away. The point that is equidistant from those three landmasses ends up in the middle of the ocean, far from any shipping route or flight path.

The area is also part of the South Pacific Gyre, a huge rotating current that traps floating debris and nutrients. This makes the water very clear but also low in nutrients, so there is less marine life compared to other parts of the ocean. The lack of human activity and the extreme distance from land make Point Nemo a useful location for space agencies: it is a “spacecraft cemetery.” Decommissioned satellites and space stations, including the Russian Mir space station and several cargo spacecraft, have been deliberately crashed into the ocean near Point Nemo because it is the safest place on Earth to do so, far from any populated areas.

How Is the Distance Calculated?

Calculating the distance from Point Nemo to land requires knowing the coordinates of the nearest land and using the haversine formula or a similar great-circle distance calculation. The haversine formula is:

a = sin²(Δφ/2) + cos φ1 ⋅ cos φ2 ⋅ sin²(Δλ/2)

c = 2 ⋅ atan2(√a, √(1−a))

d = R â‹… c

where φ is latitude, λ is longitude, R is Earth’s mean radius (6,371 km), and d is the distance between the two points. In the calculator above, you can enter any distance in kilometers and convert it to miles or nautical miles, which is useful if you are comparing distances or planning a voyage. The default value of 2,688 km is the actual distance from Point Nemo to the nearest land.

To find Point Nemo itself, surveyors used a computer algorithm that iteratively searched the globe for the point that maximizes the minimum distance to any land. That is a more complex problem than a single distance calculation, but the result is a set of coordinates that are now widely accepted.

Common Misconceptions

One common misconception is that Point Nemo is the farthest point from any human being. That is not true, because astronauts in orbit are often closer. Another misconception is that Point Nemo is the deepest part of the ocean. It is not—the deepest point is the Mariana Trench, which is thousands of kilometers away. The depth at Point Nemo is about 4,000 meters (13,000 feet), which is deep but not exceptional.

People also sometimes think that Point Nemo is completely lifeless. While the water is low in nutrients, there are still marine organisms, including bacteria and some fish. The area is not a dead zone, but it is less productive than coastal waters. Finally, some believe that Point Nemo is a single fixed point that never changes. In fact, because coastlines change slowly due to erosion and sea-level rise, the exact location of Point Nemo can shift slightly over geological timescales. For practical purposes, the coordinates are fixed, but the definition is based on current coastlines.

Frequently Asked Questions

Can you visit Point Nemo?

Technically yes, but it is extremely difficult. The nearest land is over 1,600 miles away, and there are no regular ship routes to the area. You would need a specialized research vessel or a private yacht capable of a long ocean crossing, and you would need to carry all your supplies. There is no dock, no shelter, and no rescue service nearby. A few expeditions have visited the area, but they are rare and expensive.

Why is it called Point Nemo?

The name comes from Jules Verne’s fictional character Captain Nemo, the commander of the submarine Nautilus in “Twenty Thousand Leagues Under the Sea.” The name was suggested by Lukatela, who chose it because “nemo” means “no one” in Latin, fitting the remoteness of the location. It is not named after the Disney fish.

What is the closest land to Point Nemo?

The closest land is actually three landmasses at roughly equal distances: Ducie Island, Motu Nui, and Maher Island. All are about 2,688 kilometers away. Ducie Island is an uninhabited atoll in the Pitcairn Islands, Motu Nui is a small rocky islet near Easter Island, and Maher Island is a small island off the coast of Antarctica.

How deep is the ocean at Point Nemo?

The ocean depth at Point Nemo is about 4,000 meters (13,000 feet). This is deep but not the deepest point in the ocean. The depth varies slightly because the seafloor is not flat, but it is typical for the abyssal plain of the South Pacific.

Why is Point Nemo used as a spacecraft cemetery?

Because it is the most remote place on Earth, it is the safest place to crash decommissioned spacecraft. The risk of hitting a person or a ship is extremely low, and the area is far from any populated land. Several spacecraft have been deliberately de-orbited there, including the Russian Mir space station in 2001 and many cargo ships for the International Space Station.

Is Point Nemo the same as the Pacific pole of inaccessibility?

Yes, Point Nemo is the official name for the Pacific Ocean’s pole of inaccessibility, which is the point in the ocean farthest from any land. There are other poles of inaccessibility for other oceans, such as the Arctic and the Indian Ocean, but Point Nemo is the most famous because it is the most remote.
