Earth Sandwich / City antipodes / Panjin

Antipode finder · China

The antipode of
Panjin.

Draw a straight line from Panjin (41.12° N, 122.07° E) through the centre of the Earth and it comes out at 41.12° S, 57.93° W, in the South Atlantic Ocean, 287 km from the nearest dry land, off the coast of Argentina. The other slice of an Earth sandwich would sink.

Two globes: one centred on Panjin, one centred on its antipode at 41.12° S, 57.93° W

Can you make an Earth sandwich from Panjin?

No, not from Panjin itself. The other slice would land in the South Atlantic Ocean, 287 km from the nearest dry land (Argentina), where the sea floor lies about 120 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 318 km from Panjin, 54 km from Lüshun, China. Its other slice would go down 35 km from Necochea, Argentina.

How this was worked out: the antipode flips the latitude and moves the longitude by 180°. Land or sea comes from the OpenStreetMap coastline the map uses; the sandwich verdict and elevations come from the verifier's 0.2° grid (Natural Earth land, ETOPO 2022 relief); water names from Natural Earth; towns and populations from GeoNames. The city's position is GeoNames' point for it; a big city's suburbs spread tens of kilometres around that point, and the figures move with them. Generated 2026-09-29.
