Earth radius (denoted as R 🜨 or R E) 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 (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 ...
The standard acceleration of gravity for Earth is defined (CODATA 2018) as 9.80665 m/s 2 (exact).
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).
Earth radius (represented as R 🜨 or ) 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) ( equatorial radius , represented a ) to a minimum of nearly 6,357 km (3,950 mi) ( polar radius , represented ...
6 lip 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).
The calculator below calculates Earth radius at a given latitude. In fact, of course, it calculates the radius of WGS 84 reference ellipsoid at a given latitude, and if you want some theory recap, you can find it below the calculator.
Earth's circumference is the distance around Earth. Measured around the equator, it is 40,075.017 km (24,901.461 mi). Measured passing through the poles, the circumference is 40,007.863 km (24,859.734 mi). [1] Measurement of Earth's circumference has been important to navigation since ancient times.
