# You are closer to space than to the sea

Space begins 100 km above your head. For 80% of the world's land, the sea is farther than that. Type your town and see which is nearer, measured along the globe.

## How much of the world's land is closer to space?

On the map, every place on land takes the colour of the winner: violet where space is nearer, teal where the sea is. With space at 100 km, violet covers **80%** of the land. The sea wins only on a strip along the coasts and on most islands.

Move the space line and watch the map change. At 80 km, close to the 50-mile threshold used by the US aviation regulator, the sea wins even less: 18% of the land. Only when you raise the line to the height of the International Space Station, around 400 km, does the violet shrink to the interiors of the continents and the largest islands.

## How many people live closer to the sea than to space?

People are not spread evenly over the land. The 100 km strip along the sea is 20% of the land, but **39%** of people live on it: 106 people per square kilometre, against 43 everywhere else. Even so, the majority, **61%**, have space nearer than the sea.

The two curves show the gap best. Half of humanity lives less than **197 km** from the sea. Half of the land is more than **394 km** away.

### At 400 km, near the space station's height, the land splits in two

394 km is a little below the height at which the International Space Station flies: 413 to 427 km at the end of September 2026, according to NASA. If space began at about 400 km, the world's land would split into two nearly equal halves: 50% nearer the sea, the rest nearer the station. People would stay lopsided: 66% of them would have the sea nearer.

## How far from the sea do Romanians live?

Romania has 225 km of coast, according to the World Factbook, for 238,391 km² of territory. Bulgaria, half its size, has 354 km. Only 8.3% of Romania lies within 100 km of the sea, and 4.9% of its residents live there, about 958,000 people. The other **95.1%** have space nearer than the sea.

Here Romania runs against the world average. Across the planet, the strip by the sea is almost twice as crowded as average; in Romania it is emptier than the rest of the country: 48 people per km², against 85 elsewhere. Apart from Constanța and the resorts, the Danube Delta and Dobruja are thinly peopled, and the other big cities are far from the shore: Galați and Brăila, on the Danube, are more than 100 km from the sea, measured to the beach at Gura Portiței. Romania is not alone. Of 89 other coastal countries with between 5% and 95% of their land within 100 km of the sea, 20 also have a smaller share of their people than of their land in that strip, among them Bulgaria, Ukraine, Germany and Italy.
- Country | of the land | of the people
- Romania | 8.3% | 4.9%
- Bulgaria | 33.7% | 25.0%
- Ukraine | 18.2% | 15.9%
- Germany | 21.5% | 13.0%
- France | 40.3% | 41.0%
- Türkiye | 40.0% | 56.2%
- Italy | 83.0% | 75.0%
- Greece | 97.6% | 99.1%
- United Kingdom | 99.5% | 99.0%
- The whole world | 20.4% | 38.7%

The place in Romania farthest from the sea is northern Bihor, by the Hungarian border: 618 km. There, space is 6 times nearer than the shore.

### The communes and towns where the sea beats space

For 152 of Romania's 3,181 local authorities, a point chosen inside the territory, near its middle, is within 100 km of the sea. Most are in Constanța (70) and Tulcea (48) counties. The other 34 are in the east of Ialomița, Călărași and Brăila counties, across the Danube: Fetești, for one, is 66 km from the sea in a straight line across Dobruja.

## Where is the sea farthest from land, and land farthest from the sea?

**On land.** The place farthest from any sea is in northern Xinjiang, China, 240 km from the city of Ürümqi: 2,476 km to the nearest shore on the coastline used here. There, space is 25 times nearer than the sea. In 2007, with a different coastline, Daniel Garcia-Castellanos and Umberto Lombardo found two nearly tied points, at 2,510 and 2,514 km; the second is also near Ürümqi. Most of the difference comes from where you decide the Gulf of Ob, in northern Siberia, ends and the river begins.

**At sea.** The point farthest from land is Point Nemo, in the South Pacific: 2,688 km to the nearest island, according to NOAA, the US ocean agency. The coastline used here gives 2,692 km. When the space station passes overhead, at about 420 km, the people aboard are 6.4 times nearer to Point Nemo than any shore is.

The Pacific, with its seas, covers 168.7 million km². All the land on Earth covers 148.9 million km². Every continent and every island would fit inside it with room to spare: nearly 20 million km².

## What counts as "the sea", and where space begins

**Space.** It has no physical edge: the air thins out gradually. The Fédération Aéronautique Internationale (FAI), which keeps aviation and spaceflight records, uses 100 km, the Kármán line. In the US, the Federal Aviation Administration recognises people who pass 50 miles, or 80.47 km, on a flight it has licensed or permitted, and in 2018 the astronomer Jonathan McDowell argued for about 80 km. This page uses 100 km and also shows 80 km. The line is measured from sea level. The page ignores the height of the place: a town 1,000 m up is in fact 1 km nearer space.

**The sea.** The world ocean and every sea joined to it: the Black Sea (through the Bosphorus), Azov, Marmara, the Baltic, the Mediterranean. The Caspian has no natural link to the ocean, so in this calculation it counts as neither sea nor land; lakes count as land. Lagoons cut off from the sea by a sand bar or a dam, joined to it at most through sluices, count as lakes: Razim–Sinoe in Romania, Sasyk and Shagany–Alibei in Ukraine. The base map, Natural Earth, draws them open to the sea; left that way, they would have put Cluj's "sea" in Lake Razim.

**Distance.** A straight line along the Earth's surface, on the great circle, to the nearest point of the shore, on a sphere of radius 6,371 km. On the ellipsoid the difference is under 0.5%. The coastline is Natural Earth at 1:10 million; a more detailed map would give slightly different distances. When the sea and space are less than 1.5 km apart, the page calls a tie.

**People.** The GHSL population grid from the European Commission's Joint Research Centre, estimated for 2025 in squares of about 1 km, summed here into 2.5-arc-minute squares: 8.19 billion people, of whom 19.4 million in Romania. It is a modelled estimate, not a census. Other studies give smaller figures for the "coastal population" because they add a condition: Kummu and colleagues (2016) count only people who also live less than 100 m above sea level, on other population data, and find 27% in 2010.

## Method and sources

For every 2.5-arc-minute square of land (about 4.6 km at the equator) we measured the distance along the globe to the nearest point of the shore, on a coastline densified to one point per kilometre. The land share is weighted by each square's true area. The people share sums the GHSL grid over the same squares.

The distance for your town is computed on the page, on a simplified coastline (at most 1.1 km off the full one, checked on 300 points). The same coastline and the same calculation are tested in Python and in the browser and give the same values.

For Romania, every square of about 1 km in the GHSL grid was assigned to the local authority it falls in. Place names come from the INS register; the search uses GeoNames.
