Mount Everest is not the farthest point from Earth's centre: This South American mountain holds that record

Ask almost anyone to name the highest point on Earth and the answer will likely be Mount Everest. Towering above the Himalayas at 8,848 metres (29,029 feet), Everest has long been celebrated as the world's tallest mountain. Climbers dream of reaching its summit and geography textbooks have cemented its place in popular imagination.Yet there is another mountain that holds a remarkable record. Hidden among the Andes of Ecuador, Mount Chimborazo stands thousands of metres shorter than Everest. Despite that, its summit is actually farther from the centre of the Earth than any other point on the planet's surface. The reason has less to do with the mountain itself and more to do with the shape of the world beneath our feet.Mount Chimborazo rises to about 6,263 metres (20,548 feet) above sea level. By most measures, that is impressive but nowhere near Everest's height.What makes Chimborazo special is its location. The mountain sits just south of the Equator, where Earth is at its widest. Many people imagine the planet as a perfect sphere, but it is slightly flattened at the poles and bulges outward around the Equator.This bulge means that locations near the Equator are naturally farther from Earth's centre. Chimborazo benefits from that extra distance. Even before the mountain begins to rise, the ground beneath it is already positioned farther from the planet's centre than many other places on Earth.When scientists calculate the distance from Earth's centre to mountain summits, Chimborazo comes out on top. Its peak is about 2,072 metres (6,800 feet) farther from the centre of the planet than the summit of Mount Everest.That distinction has earned Chimborazo a unique description. It is often called the point on Earth closest to outer space.Everest does not lose its most famous title. It remains the highest mountain above sea level.Sea level is the standard reference used to measure elevation around the world. From that baseline, Everest stands higher than any other mountain. Its summit rises nearly 2.6 kilometres above Chimborazo's peak.For climbers, explorers and geographers, that measurement remains extremely important. Reaching Everest's summit still means standing at the highest elevation on Earth.The difference lies in what is being measured. One record is based on height above sea level. The other is based on distance from the centre of the planet.The reason Chimborazo beats Everest can be understood with a simple example.Imagine two people standing on different platforms. One person stands on a shorter ladder placed on a higher platform. The other stands on a taller ladder placed on a lower platform. Even though the second ladder is taller, the first person may still end up farther from the ground.Something similar happens with Chimborazo and Everest. Everest is the taller mountain. Chimborazo sits on a part of Earth that is already farther from the centre because of the Equatorial bulge.That small difference in Earth's shape is enough to change the outcome.The debate over Earth's highest mountain becomes even more interesting when another definition is introduced.Deep in Hawaii lies Mauna Kea, a dormant volcano that rises from the floor of the Pacific Ocean. Most of the mountain remains hidden beneath the water. Only its summit is visible above the surface.When measured from its underwater base to its peak, Mauna Kea stretches more than 10,210 metres (33,500 feet). That makes it taller from base to summit than Everest.As a result, three different mountains can each claim a version of the world's highest-mountain title.Everest is the highest above sea level. Chimborazo is the farthest point from Earth's centre. Mauna Kea is the tallest from base to peak.The story of Mount Chimborazo is a reminder that even familiar facts can have unexpected twists. For generations, Everest has symbolised the highest place on Earth. Yet a closer look at the planet reveals a more fascinating picture.Because Earth is not a perfect sphere, the answer depends on where you start measuring. Viewed from the planet's centre, the summit of Chimborazo reaches farther into space than any other point on Earth.It is a little-known geographical fact. Yet it offers a striking lesson about the shape of our world and the hidden stories behind some of its most famous landmarks.
