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).
The standard acceleration of gravity for Earth is defined (CODATA 2018) as 9.80665 m/s 2 (exact).
Sep 29, 2020 · The Earth has a radius of 2.439 kilometers / 1.516 miles and a diameter of only 12.742 km / 7.917 mi. When it comes to weight, the mass of Earth is equivalent to 5.9 quadrillion kg.
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...
Feb 15, 2023 · Compute the radius of the Earth using the formula C (circumference) = 2 x pi x r (radius). Eratosthenes’ methods result in a formula that would look like this: 39,350 = 2 x 3.14 x r, or 6,267 kilometers.
Oct 22, 2020 · Its equatorial radius is 6378 km, but its polar radius is 6357 km - in other words, the Earth is slightly flattened. Eratosthenes was measuring the polar radius, and his value (using the 0.15 km/stadium conversion) lies between the polar and equatorial values.
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).
Dec 24, 2015 · The equatorial diameter of the Earth is 12,756 km. This is the diameter of the Earth measured from one side of the Earth, passing through the center.
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 ...
Jan 12, 2023 · ( C = 2πr) With this information, Eratosthenes inferred that the Earth’s radius was 6366 km. Both of these values are very close to the accepted modern values for the Earth’s circumference and radius, 40,070 km and 6378 km respectively, which have since been measured by orbiting spacecraft.
