Equatorial bulge

Equatorial bulge by Wikipedia Bot 0
The equatorial bulge refers to the phenomenon where a planet, such as Earth, is not a perfect sphere but an oblate spheroid. This means that the planet's diameter is slightly larger at the equator than it is at the poles due to its rotation. As a planet rotates, centrifugal force acts outward from its axis of rotation, which causes the material at the equator to bulge outwards.
