When the equatorial diameter of a spheroid is larger than the polar diameter, it is called an oblate spheroid. This shape is characteristic of rotating bodies, like the Earth, which bulge at the equator due to centrifugal forces while being slightly flattened at the poles. The Earth's shape is a prime example of an oblate spheroid, as its equatorial diameter is about 43 kilometers larger than its polar diameter.
