Earth Sandwich / City antipodes / Madinah

Antipode finder · Saudi Arabia

The antipode of
Madinah.

Draw a straight line from Madinah (24.47° N, 39.61° E) through the centre of the Earth and it comes out at 24.47° S, 140.39° W, in the South Pacific Ocean, 295 km from the nearest dry land. The other slice of an Earth sandwich would sink.

Two globes: one centred on Madinah, one centred on its antipode at 24.47° S, 140.39° W

Can you make an Earth sandwich from Madinah?

No, not from Madinah itself. The other slice would land in the South Pacific Ocean, 295 km from the nearest dry land, where the sea floor lies about 4,520 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 307 km from Madinah, 32 km from Jeddah, Saudi Arabia. Its other slice would go down 403 km from Otepa, French Polynesia.

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.
