Its antipode
…
What's on the other side of the Earth?
Every place on Earth has an antipode: the point you'd reach by digging straight down through the centre of the planet and out the far side. To find it, flip the latitude to the other hemisphere and turn the longitude halfway round the globe. This antipode map does it for any address, city or point you click, and shows the two places side by side on synced maps: pan one and the other follows, mirrored through the Earth's core.
Most digs end in water. Roughly 71% of the surface is ocean, and the big northern landmasses sit opposite the Pacific and Indian Oceans, so from most of North America, Africa and Europe you'd come up at sea. The tool tells you which ocean, and how far it is to the nearest land. There are famous exceptions: Spain and Portugal sit opposite New Zealand, much of China lands in Argentina and Chile, and Hawaii's antipode is in Botswana.
For the bigger picture, switch on the antipodal land overlay. It draws every country flipped onto its antipodes in translucent teal, so wherever teal covers land, that land has land on the other side of the world. Download either view as a PNG, or send the pair to Mapimator Studio to animate a flight halfway round the globe and back down to your antipode.
Frequently asked questions
What is an antipode?
The antipode of a place is the point exactly opposite it on the globe, where a straight line from it through the centre of the Earth comes out. Its latitude is the same number in the other hemisphere and its longitude is 180° away: the antipode of 40° N, 4° W is 40° S, 176° E.
If I dug a hole through the Earth, where would I come out?
At your antipode, and for most people that's the ocean. Dig from Madrid and you'd surface in New Zealand's North Island; dig from Beijing or Shanghai and you'd come out in Argentina; but from most of the United States, Canada, Africa and Europe you'd land in the Pacific or Indian Ocean. The hole would be 12,742 km deep, straight through the core.
How much land has land on the other side?
Surprisingly little. Because most of the planet is ocean, only about 15% of the land surface is antipodal to other land, around 4% of the whole Earth. The biggest overlaps are South America with China and Southeast Asia, and New Zealand with Spain and Portugal. Switch on the antipodal land overlay to see every continent mirrored onto the map.
How far away is my antipode?
Every antipode is the farthest point on Earth from its place: about 20,000 km over the surface, half the planet's circumference, whichever direction you travel. Through the centre it's the Earth's diameter, about 12,742 km. If a frictionless tunnel existed, falling through it would take about 42 minutes.
How does the tool decide land or ocean?
It checks the antipode against world country outlines. If it falls in the sea, it names the ocean and finds the nearest coastline with its distance. The outlines are simplified, so very small islands can be missed and points within a few kilometres of a coast are approximate.
