  • Earth radius - Wikipedia
    Approximating the figure of Earth by an Earth spheroid (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of about 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi)
  • Radius of Earth in Km, Meters, Miles - Adda247
    The radius of Earth is approximately 6,371 kilometers (or about 3,959 miles) This value represents the distance from the center of the Earth to the outer boundary, which is the Earth’s surface
  • What is the radius of the earth? - The Institute for Environmental . . .
    The Earth’s radius is approximately 6,371 kilometers (3,959 miles), representing the distance from the Earth’s center to a point on its surface However, due to Earth’s slightly flattened, ellipsoidal shape, this value is an average; the radius varies depending on the location measured
  • Earth Radius - University of South Florida
    The radius of Earth at the equator is approximately 6378137 m, using the WGS84 ellipsoid Earth can be thought of as a flattened oblate ellipsoid, with a larger radius at the pole than at the equator
  • Earth Fact Sheet - University of Colorado Boulder
    Equatorial radius (km) 6378 1 Polar radius (km) 6356 8 Volumetric mean radius (km) 6371 0 Core radius (km) 3485 Ellipticity (Flattening) 0 00335 Mean density (kg m 3) 5515
  • What is the Earth radius? - Telescope Nerd
    The radius of Earth is 6,371 kilometers (3,959 miles) and its mass is 5 972 x 10^24 kilograms (1 316 x 10^24 pounds) Earth’s equatorial radius measures 6,378 km (3,963 miles), while its polar radius is 6,357 km (3,950 miles)
  • Geoid - Earth Dimensions, Radius, Mass Density | Britannica
    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
  • The Earth - Imagine the Universe!
    Note: The Earth is almost, but not quite, a perfect sphere Its equatorial radius is 6378 km, but its polar radius is 6357 km - in other words, the Earth is slightly flattened
  • 56. 2: Radius of the Earth - Physics LibreTexts
    There is a useful formula that gives the radius of the Earth R at any latitude ϕ : (56 2 1) R (ϕ) = (a 2 cos ϕ) 2 + (b 2 sin ϕ) 2 (a cos ϕ) 2 + (b sin ϕ) 2 where, as before, the equatorial radius a = 6378 1370 km, and the polar radius b = a (1 f) = 6356 7523142 km (WGS 84)
  • Earth radius explained
    What is Earth radius? Earth radius is the distance from the center of Earth to a point on or near its surface
