The geographical center of Earth is the location on the surface of Earth where the sum of distances to all locations on land is the smallest. If you had an airplane with an infinite energy resource and fly from one start location on Earth to one locations on a land surface somewhere on Earth and back again and repeat that from the same start location to all possible destination locations, the starting locations where the total travel distance sums up as the smallest, marks the geographical center of Earth. In 2003, Holger Isenberg's study revealed the center to be located at coordinates of: 40°52′N34°34′E , in Turkey, near the district of İskilip, Çorum Province, approx. 200 km northeast of Ankara Ankara.
