Is the Geometric Center of the Earth Located in Egypt?

The geometric center of the Earth is known by many other terms, such as, the geographical center, the centroid, and in some cases, the barycenter. It is defined as the center of all land surfaces on Earth. Experts have differed greatly as to how to calculate the geometric center of our planet. According to some, it is the center of gravity, taking into consideration the mass distribution provided by each piece of land as a zone of thin layer of equal density.

Where is the geometric center of our planet?

The location of the Great Pyramid of Giza in Egypt has long since been considered to be the spot marked the geographical center of the Earth. Its East-West axis conforms with the longest land parallel across Earth, by passing through the continents, African, Asia and America. Likewise, the longest land meridian of the Earth passes through Asia, Africa, Europa, and Antarctica, crosses across the Pyramid as well.

Back in 1864, an astronomer from Scotland, Charles Piazzi Smyth, tagged the Great Pyramid the prime meridian because of this very reason: the location would imply that it would cross through the most amount of land. However, his point of view was not accepted by the majority of the committee that was to ultimately decide to vote for the Greenwich on the basis that many ships would dock at the port of London.

Throughout time, the Great Pyramid of Giza has been called the geographical center of the planet, based on the scientific calculations. But, the issue remained controversial for years after.

During the recent years, the subject has continued to be a bone of contention among experts. In 2007, Susan Wise Bauer, an American author, stated that the theory involving the Great Pyramid would only be true if a cylindrical map projection were to be used as map of the Earth.

In 2003, more sophisticated methods were used for the purpose of the calculations and the result obtained was a spot 180 km northeast of Ankara, Turkey. This result was found to be similar to that of a physicist who did the calculations back in 1973, Andrew Woods. The spot in Ankara is determined to be the most accurate point representing the geometric center of the Earth by many.
