The Earth: Suppose no atmosphere Earth is in equilibrium BB radiation out = sunlight in Earth has an albedo of 30%; this proportion of incoming light is reflected and does not contribute to heating of earth. In diagram form: Note: divide by 4 due to spherical shape of earth. Also, flux from earth’s core is negligible relative to flux from sun.
