Terrestrial radii refer to the measurements of the Earth's radius, which is approximately 6,371 kilometers (3,959 miles) when averaged. This value can vary slightly based on whether it's measured from the equator, where the Earth bulges due to its rotation, or from the poles, where it is slightly flattened. The equatorial radius is about 6,378 kilometers (3,963 miles), while the polar radius is about 6,357 kilometers (3,950 miles). These variations are important for understanding Earth's shape and its gravitational field.
