Summary
[edit]DescriptionCloudlessgasgiant.jpg |
English: Gaseous giants with equilibrium temperatures between about 350 K (170°F, 80 °C) and 800 K (980 °F, 530 °C) do not form global cloud cover, because they lack suitable chemicals in the atmosphere to form clouds. (They would not form sulfuric acid clouds like Venus due to excess hydrogen.) These planets would appear as featureless azure-blue globes because of Rayleigh scattering and absorption by methane in their atmospheres, appearing like Jovian-mass versions of Uranus and Neptune. Because of the lack of a reflective cloud layer, the Bond albedo is low, around 0.12 for a class-III planet around a Sun-like star. They exist in the inner regions of a planetarysystem, roughly corresponding to the location of Mercury.Possible class-III planets are HD 37124 b, HD 18742 b, HD 178911 Bb, 55 Cancri c, Upsilon Andromedae c, Kepler-89e, CoRoT-9b, HD 205739 b and Pollux b. Above 700 K (800°F, 430 °C), sulfides and chlorides might provide cirrus-like clouds. |
