Earth's Polar Radius
Earth's polar radius is the distance from Earth's center to either geographic pole, के बराबर लगभग 6,356.752 km (3,949.90 miles) according to the WGS 84 reference ellipsoid. It is shorter than the equatorial radius due to Earth's oblate spheroid shape, a flattening caused by the planet's rotation. The difference between the equatorial and polar radii defines Earth's flattening factor, a key parameter in geodesy.
