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). Therefore, the diameter of Earth through its...
6.3781 × 106 m [1] Metric system. 6,357 to 6,378 km. English units. 3,950 to 3,963 mi. Earth radius is sometimes used as a unit of measurement in astronomy and geophysics. The International Astronomical Union recommends that the radius at the equator should be used.
Sep 26, 2022 · In scientific notation, the radius of the earth in meters is equal to 6.37×106 meters or approximately 6.4×106 meters, and 6378100 or approximately 6370000 in standard form. Asked By: Lena Frontelo | Last Updated: 18th May, 2020, Earth is the third planet from the sun.

With a radius of 3,959 miles (6,371 kilometers), Earth is the biggest of the terrestrial planets and the fifth largest planet overall.
Earth dimensions—radius, mass, and 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.
