Which summit is farthest from Earth's center?

Chimborazo is the summit farthest from Earth’s centre.

The Ecuadorian volcano reaches about 6,263 metres above sea level, far below Mount Everest’s 8,849 metres. Yet Chimborazo stands almost on the Equator, where Earth’s rotation causes the planet to bulge outward. That wider equatorial radius places its summit roughly 6,384.4 kilometres from Earth’s centre—about 2.1 kilometres farther than Everest’s summit.

This distinction explains why “highest” depends on the measurement used. Everest is the highest summit above sea level, while Chimborazo is the farthest from the planet’s centre. Chimborazo is also Ecuador’s highest mountain, and its last known eruption is generally dated to around AD 550.

Peru’s Huascarán is a very close competitor, and differences in survey data and geoid models have produced small variations in rankings. Even so, Chimborazo is the conventional and canonical answer to this wording. The peak was first climbed by Edward Whymper and companions in 1880.
