- Saturn is even further at 1434X109m from the sun. Calculate the approximate strength of the greenhouse effect on Jupiter. The observed surface temperature is 133K, the albedo is 0.47, the solar constant is 15W/m2.(b) Show that the equilibrium temperature of Venus is right for liquid water, given that it lies = 3.85 × 1026 W) and assuming a at a distance of d = 1.09 × 108 km from the Sun (Lo mean albedo of 0.45. Explain why, in reality, Venus is too hot for liquid water.9)
