Almost everyone knows that Mount Everest is the highest mountain in the world. Climbers from everywhere travel to Everest hoping to earn the distinction of climbing the "World's Highest". The peak of Mount Everest is 8,848 meters (29,028 feet) above sea level. This high elevation gives Mount Everest the distinction of being the mountain with the highest altitude.

But not many people know about Mt Chimborazo in Ecuador with an altitude of 6,310 meters (20,703 feet), which is less than Mount Everest; however, Chimborazo has the distinction of being the highest mountain above Earth's center. This is because Earth is not a sphere - it is an oblate spheroid. As an oblate spheroid, Earth is widest at its equator. Chimborazo is just one degree south of Earth's equator and at that location it is 6,384 kilometers from Earth's center or about 2 kilometers farther from Earth's center than Mount Everest.

Ecuadorians find pride in this interesting fact. Nonetheless, Chimborazo cannot compare in difficulty, lack of oxygen, nor in fame, to Mount Everest.
