Equatorial bulge
An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centrifugal force exerted by the rotation about the body's axis. A rotating body tends to form an oblate spheroid rather than a sphere.

Equatorial bulge
An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centripetal force of its rotation. A rotating body tends to form an oblate spheroid rather than a sphere. The Earth has an equatorial bulge of 42.72 km: that is, its diameter measured across the equatorial plane is 42.72 km more than that measured between the poles. An observer standing at sea level on either pole, therefore, is 21.36 km closer to Earth's centrepoint than if standing at sea level on the equator. The value of Earth's radius may be approximated by the average of these radii. An often-cited result of Earth's equatorial bulge is that the highest point on Earth, measured from the center outwards, is the peak of Mount Chimborazo in Ecuador, rather than Mount Everest. But since the ocean, like the Earth and the atmosphere, bulges, Chimborazo is not as high above sea level as Everest is. Basing this on centripetal force, the relationship applies. Viewing the globe as a series of rotating discs, the mass M and radius R at the poles get very small at the same time and thus produce a smaller force for the same velocity.
