- Planets of other classes sometimes have rain composed of other compounds. An example is the class N Venus, which rains sulfuric acid.
This has been uncited, and seems very apocryphal, as Venus' class has never been stated, nor has any reference to "sulfuric acid" in any episodes. --Alan 03:02, 1 August 2007 (UTC)
- Yeah, this was the first article I ever wrote, before I understood half of the rules around here. I will say that at the time I wrote it, the MA article for Venus stated it was class N, which led me astray. I am pretty sure we have had examples of planets with rain other than water, though none come immediately to mind. Can anyone else help think of them? --OuroborosCobra talk 03:10, 1 August 2007 (UTC)
"Rain" by definition is composed of water: Water that is condensed from the aqueous vapor in the atmosphere and falls to earth in drops more than 1/50 in. (0.5 mm) in diameter. Another substance falling from the sky, say sulfur, would have to have an entirely different name.
