1. The problem statement, all variables and given/known data Suppose we place a perfectly black sphere (i.e., a sphere that absorbs all energy it receives) with radius 2500 km at a distance of 5.2 AU from the Sun. How much energy does the sphere absorb in one second? energy emitted by sun is given to be 3.90 * 10^26 2. Relevant equations flux = energy emitted(luminosity)/Area 3. The attempt at a solution I found the area of the black sphere and the area of the energy emitted. But I do not no what the next step should be. would i need to find the flux of the black sphere first then find how much energy it receives. I am not looking for a solution to the question but how I would go about trying to solve it. Can someone please help.
