Earth effective radius
WebEarth receives almost all its energy from Sun – only a small amount of geothermal heating. ... Note ‘a’, the radius of the Earth, does not appear. 4. Figure 4: The spinning Earth is imagined to intercept solar flux over a disk and radiate terrestrial energy away isotropically from the sphere. Modified from Earth radius (denoted as R🜨 or $${\displaystyle R_{E}}$$) 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, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) (equatorial radius, denoted a) to a minimum of nearly 6,357 km … See more Earth's rotation, internal density variations, and external tidal forces cause its shape to deviate systematically from a perfect sphere. Local topography increases the variance, resulting in a surface of profound complexity. Our … See more The following radii are derived from the World Geodetic System 1984 (WGS-84) reference ellipsoid. It is an idealized surface, and the Earth measurements used to calculate it have an uncertainty of ±2 m in both the equatorial and polar dimensions. … See more The mathematical expressions above apply over the surface of the ellipsoid. The cases below considers Earth's topography, above or below a reference ellipsoid. As such, they are topographical geocentric distances, Rt, which depends not only on latitude. See more The first published reference to the Earth's size appeared around 350 BC, when Aristotle reported in his book On the Heavens that mathematicians had guessed the circumference … See more Geocentric radius The geocentric radius is the distance from the Earth's center to a point on the spheroid surface at See more The Earth can be modeled as a sphere in many ways. This section describes the common ways. The various radii derived here use the notation and dimensions noted above for the Earth as derived from the WGS-84 ellipsoid; namely, Equatorial radius: a … See more Earth's diameter is simply twice Earth's radius; for example, equatorial diameter (2a) and polar diameter (2b). For the WGS84 ellipsoid, that's respectively: • 2a … See more
