Approximating the figure of Earth by an Earth spheroid (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of nearly 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi).
Jul 6, 2021 · According to NASA, Earth's radius at the equator is 3,963 miles (6,378 kilometers), while the radius at the poles is 3,950 miles (6,356 km).
Find the equatorial radius, polar radius, and volumetric mean radius of Earth, as well as other bulk parameters, orbital elements, and atmospheric data. The equatorial radius of Earth is 6378.137 km, and the polar radius is 6356.752 km.
Objects must orbit Earth within this radius, or they can become unbound by the gravitational perturbation of the Sun. Earth, along with the Solar System, is situated in the Milky Way and orbits about 28,000 light-years from its center.
Earth radius is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) to a minimum of nearly 6,357 km (3,950 mi).
With a radius of 3,959 miles (6,371 kilometers), Earth is the biggest of the terrestrial planets and the fifth largest planet overall.
Geoid - Earth Dimensions, Radius, Mass & Density: As previously noted, terrestrial arc measurements are capable of yielding a value of the equatorial radius of Earth, but satellite measurements are greatly superior for determining the flattening.
