Venus receives about 3.03 x 1017 W from the Sun. Due mostly to highly reflective sulfuric acid clouds in its upper atmosphere, it absorbs only about 30% of the incoming light energy. Venus' total surface area is about 4.60 x 1014 m2. What would Venus' temperature need to be, in kelvin, in order to re-radiate all of the light energy it receives from the Sun each second, if it were a perfect blackbody with no greenhouse effect?
