Earth Sandwich / City antipodes / Manhattan

Antipode finder · United States

The antipode of
Manhattan.

Draw a straight line from Manhattan (40.78° N, 73.97° W) through the centre of the Earth and it comes out at 40.78° S, 106.03° E, in the Indian Ocean, 1,070 km from the nearest dry land, off the coast of Australia. The other slice of an Earth sandwich would sink.

Two globes: one centred on Manhattan, one centred on its antipode at 40.78° S, 106.03° E

Can you make an Earth sandwich from Manhattan?

No, not from Manhattan itself. The other slice would land in the Indian Ocean, 1,070 km from the nearest dry land (Australia), where the sea floor lies about 4,360 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 2,458 km from Manhattan, 34 km from Lamar, United States. Its other slice would go down 1,410 km from Port-aux-Français, French Southern Territories.

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.
