Earth's Equatorial Radius
Earth's equatorial radius is the distance from Earth's center to its surface at the equator, sama dengan kira-kira 6,378.137 km (3,963.19 miles) as defined by the WGS 84 reference ellipsoid. Because Earth is an oblate spheroid, the equatorial radius is the largest radius and is about 21 km greater than the polar radius. It is a fundamental constant in geodesy, navigation, and geophysical sciences.
