Earth's Polar Radius
Earth's polar radius is the distance from Earth's center to either geographic pole, sama dengan kira-kira 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.
