WebMay 2, 2024 · The mean radius of the earth’s orbit is 1.5 × 10 11 m. The solution provided by the book uses the following P = P A × A = P A × 4 π r 2 = ( 1.4 kW) × 4 π ( R earth) 2 Once we get the power, one can simply convert that amount of energy loss per time into mass loss per time, through the identity m = E / c 2. WebOct 22, 2024 · (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.
