This Letter conveys the results of model calculations of the exospheric temperature of Jupiter and Saturn as a function of the solar cycle. These computations indicate that the maximum difference between the exosphere and mesopause temperatures is less than 100°K for both planets, compared with approximately 2000°K for the earth. Spectroscopically H<sub>2</sub>, CH<sub>4</sub>, and NH<sub>3</sub> have been detected in the Jovian atmosphere, while in the atmosphere of Saturn, H<sub>2</sub> and CH<sub>4</sub> have been positively identified. Postulating the addition of the inert gas He, it is generally assumed that these gases constitute the major components of the atmospheres of these planets.
