What is the highest point on Earth as measured from Earth's center?

The top of Mount Chimborazo is farther from the Earth's center than Mount Everest.

Mount Everest, located in Nepal and Tibet, is usually said to be the highest mountain on Earth. Reaching 29,029 feet at its summit, Everest is indeed the highest point above global mean sea level—the average level for the ocean surface from which elevations are measured. But the summit of Mt. Everest is not the farthest point from Earth’s center.

Earth is not a perfect sphere, but is a bit thicker at the Equator due to the centrifugal force created by the planet’s constant rotation. Because of this, the highest point above Earth’s center is the peak of Ecuador’s Mount Chimborazo, located just one degree south of the Equator where Earth’s bulge is greatest. The summit of Chimborazo is 20,564 feet above sea level. However, due to the Earth’s bulge, the summit of Chimborazo is over 6,800 feet farther from the center of the Earth than Everest’s peak. That makes Chimborazo the closest point on Earth to the stars.  

You may be surprised to learn that Everest is not the tallest mountain on Earth, either. That honor belongs to Mauna Kea, a volcano on the Big Island of Hawaii. Mauna Kea originates deep beneath the Pacific Ocean, and rises more than 33,500 feet from base to peak.

What does this have to do with the OCEAN service?

The National Geodetic Survey (part of the National Ocean Service) measures and monitors our ever-changing planet by mapping its gravity field and determining the precise location of points on Earth’s surface. Measurements of the Earth contribute to a wide range of important activities, including mapping and charting, navigation, flood risk determination, transportation, land use, and ecosystem management.
