    100 years plus of science fiction and I don;t think anyone anticipated this:

    COROT 7B is only about 1.6 million miles from it's sun - COROT 7.

    It's a rocky planet like Earth (but much bigger) and it's so fucking hot on the surface of the planet that it vaporises rock.

    Which based on the computer models, then falls from the sky as pebbles. Since COROT 7B has one side which faces the sun constantly, I assume rock is constantly vaporising on the day side and condensing out around the terminator.

    So the whole planet must be constantly reforming.

    So does this mean there are clouds of gaseous rock roaming around the planet's atmosphere?

    That’s fucking incredible.

    I wouldn't be surprised if Hal Clement had anticipated this. Several of his books featured big worlds with extreme conditions.

    Close to Critical had a heavy-G world with a dense atmosphere such that it was trivially easy for water to evaporate. The landscape changed on an almost daily basis.

    Presumably the surface underneath the vaporising rock is molten so it probably just flows continuously in and is replaced by rock which has precipitated out.

    Fun thought, if you had a small enough planet that the gravity was survivable and the entire planet wasn''t molten you might actually be able to put a research base on the night side.

    Thanks for posting this - just imagining rock clouds and pebble rain put a smile on my face
