Clarified Jovians fall into the range 350-900 Kelvin; Venus has a temperature of 730K at the surface but it has clouds of sulphuric acid droplets at higher altitudes where it is cooler. I'd expect most superVenus type planets to have high altitude clouds of some sort.
But if a superVenus is hot enough to be clarified completely, you should be able to see the sky from the surface- I'd expect it to be creamy white, if the atmosphere was above 40 bars. |
Thanks.
So they will be visible as engulfed in white "clouds" from the space?
And will the whiteness increase with pressure?If so, should be hot Venuses/SuperVenuses seen as brilliantly white from space?
And if you standed on the surface of such planets, will be everything engulfed in white "haze" or only the sky will be white?What would be the visibility on such a planet if the pressure is 90 bars of CO2?
BTW that was exactly the page that I was reading.
