You decide to go on an interstellar mission to explore some of the newly discovered extrasolar
planets orbiting the star ROTOR. Your spacecraft arrives in the new system, in which there are
five planets. ROTOR is identical to the Sun (in terms of its size, mass, age and composition). From
your observations of these planets, you collect the following data:

The fraction of the energy flux which is absorbed is then (1-av) = 1. - 0.76 = 0.24. So the amount of energy actually absorbed by Venus in each second is Lv = (1-av)Ev. Lv = (1-av)Ev = ___________________ ergs/s And next calculate the effective temperature of Venus: Tv4 = (Lv/(4pdv2))/s = Lv/(4spdv2) = __________________ K4 and taking the square root of Tv4 twice in succession we get the effective Temperature Tv: Tv = [Lv/(4spdv2)]0.25 = _________________ K Calculate Venus' emittance assuming that the Venus' actual temperature, Tvr, is 472o C = 745 K: ev = Lv/(4pdv2s Tvr4) = __________________ .arrow_forwardCharan is at NASA analyzing Moon rocks.
