The shape of Earth is nearly spherical. There is a small flattening at the poles and bulging around the equator due to Earth's rotation.[85] Therefore, a better approximation of Earth's shape is an oblate spheroid, whose equatorial diameter is 43 kilometres (27 mi) larger than the pole-to-pole diameter.

The equatorial diameter of the Earth is 12,756.3 kilometers, while the polar diameter of the Earth is 12,714 kilometers. The shape of the Earth is almost a perfect sphere; however, there is a small flattening at the poles and bulging around the equator due to the Earth's rotation. Therefore, a better approximation of Earth's shape is an oblate spheroid, where the equatorial diameter is 43 kilometers larger than the pole-to-pole diameter.
