The peak of one of these mountains is the point on the earth's surface which is furthest from earth's centre. Which one?
Although the summit of Mount Everest reaches a higher elevation above sea level, the summit of Chimborazo is the farthest point on the surface from Earth's center, with Huascarán a very close second. The summit of the Chimborazo is the fixed point on Earth that has the utmost distance from the center – because of the oblate spheroid shape of the planet Earth, which is "thicker" around the Equator than measured around the poles. Chimborazo is one degree south of the Equator and the Earth's diameter at the Equator is greater than at the latitude of Everest (8,848 m (29,029 ft) above sea level), nearly 27.6° north, with sea level also elevated. Despite being 2,580 m (8,465 ft) lower in elevation above sea level, it is 6,384.4 km (3,967.1 mi) from the Earth's center, 2,168 m (7,113 ft) farther than the summit of Everest (6,382.3 km (3,965.8 mi) from the Earth's center), but Chimborazo is not even the highest peak of the Andes above sea level.
