Extreme planet action

The boy likes fun facts. Even though some of the other kids like the jokes better, I try to give him what he asks for. That means today is a fact.

As if sulphuric acid rain isn't inhospitable enough, Venus has more extreme weather.



Seeker had this info to share about the strange precipitation:


"As we now understand it, the snow on Venus’ surface is probably more similar to frost. On the lower Venusian plains, temperatures reach a searing 480°C (894°F). This is hot enough that reflective pyrite minerals on the planet’s surface are vaporized, entering the atmosphere as a kind of metallic mist, leaving only the dark volcanic rocks like basalt in the Venusian lowlands."

The metals found are galena and bismuthinite.
