Earth's equatorial radius

The Earth's equatorial radius is the distance from the Earth's center to the equator. One Earth's equatorial radius is approximately 6,378.1 kilometers or about 3,963.2 miles.

The equatorial radius is the longest radius of the Earth due to its equatorial bulge, caused by the planet's rotation. This bulge results in a slightly larger radius at the equator compared to the polar radius.

The Earth's equatorial radius is used in geodesy, cartography, and satellite navigation to define the Earth's shape and for accurate measurements of distances and areas on the Earth's surface. It provides a key parameter for understanding Earth's dimensions and its gravitational field.

Earth's polar radius

The Earth's polar radius is the distance from the Earth's center to the poles. One Earth's polar radius is approximately 6,356.8 kilometers or about 3,949.9 miles.

The polar radius is shorter than the equatorial radius due to the Earth's oblate spheroid shape, which results from its rotation causing a bulge at the equator and a flattening at the poles.

The Earth's polar radius is used in geodesy, cartography, and satellite navigation to accurately describe the Earth's shape and dimensions. It is essential for understanding Earth's gravitational field, polar regions, and measurements related to the planet's overall geometry.
