Drill straight through the center of the Earth from Los Angeles, USA and you'd surface on the exact opposite side of the planet — its antipode.
Los Angeles's antipode sits at 34.05°S, 61.76°E, in the southern hemisphere, east of Greenwich. That places it in or near the Indian Ocean.
It lies roughly 20,015 km from Los Angeles — about as far apart as two points on Earth can possibly be. And the relationship is symmetric: the antipode of that spot is, of course, right back here in Los Angeles.
Like the vast majority of inhabited places, Los Angeles's antipode falls over open water rather than land — water covers about 71% of the globe, and antipodal land pairs are rare. The nearest coastline, island or settlement is what Antigea shows you when you open the live map, along with the satellite view, the closest Street View, and the local time on the other side of the world.
