Drill straight through the center of the Earth from Wellington, New Zealand and you'd surface on the exact opposite side of the planet — its antipode.
Wellington's antipode sits at 41.29°N, 5.22°W, in the northern hemisphere, west of Greenwich. That places it in or near the Atlantic Ocean.
It lies roughly 20,015 km from Wellington — 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 Wellington.
Wellington's antipode is a rare one: it actually lands on solid ground, about 1 km from Ruasna, a locality in Spain. Most cities don't get that lucky — antipodal land pairs are uncommon since water covers about 71% of the globe.
