Consequently, the surface at the equator is farther from the center of the Earth than the surface at the poles. The Earth is not a perfect sphere, but an oblate spheroid, meaning it bulges at the equator due to its rotation.

However, sea level is not perfectly uniform; it is influenced by gravitational variations, temperature, and salinity. The Atmosphere as a Boundary To truly discuss the height of Earth, one must consider the boundary where the planet's gravitational influence ends and space begins.
The exosphere, the outermost layer, gradually thins and extends up to 10,000 kilometers into space. This results in an equatorial diameter that is about 43 kilometers larger than the polar diameter.
Calculating the Mean Earth Radius of 6371 kilometers
Understanding this measurement requires looking beyond simple surface statistics and considering the dynamic forces that shape the globe. This fundamental shape dictates that the distance from the center to the surface varies significantly depending on where you are located.
