WebAccording to data taken by 183 high-school classes participating in a World Year of Physics project, "Measure the Earth with Shadows", the radius of Earth is 6563 km, compared to the accepted value for the mean radius of 6371 km. Of course, no one is claiming the size of Earth has actually changed. WebA lightbulb went on in my head. distance = earth radius * radians. Thus with some very easy algebra... radians = distance / earth radius. km radians = distance in km / 6371. mi radians = distance in mi / 3959. Sometimes …

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.

WebThe earth is not perfectly spherical, so using a single value for "radius" is an approximation. Wikipedia says "distances from points on the surface to the center range from 6,353 km to 6,384 km". It also says "Several different ways of modeling the Earth as a sphere each yield a mean radius of 6,371 km" which indicates your value. WebMay 18, 2024 · One AU is the distance from the Sun to Earth's orbit, which is about 93 million miles (150 million kilometers). When measured in astronomical units, the 886,000,000-mile (1,400,000,000-kilometer) distance from the Sun to Saturn's orbit, is a much more manageable 9.5 AU.
