WebAnother way of calculating the earth - sun distance is to look at the centrifugal and the gravitational force. This solution assumes that one already knows the mass of the sun, but thats a different problem ;-). One does only need High-School Math and Physics in order to derive a solution. Thanks to Newton we know F g = − G M m r 2 WebThe separation of Earth from the sun can be denoted R E and the mean distance can be denoted R 0, approximately 1 astronomical unit (AU). The solar constant is denoted S 0 . The solar flux density (insolation) onto a plane tangent to the sphere of the Earth, but above the bulk of the atmosphere (elevation 100 km or greater) is: bandera cubana para imprimir
