Would the atmosphere cease to exist?

    Why are you assuming it would have to freeze to fall as precipitation? You ever hear of rain?

      True, though you could have been less rude about it. I had forgotten about the condensation point. It’s pretty similar though and doesn’t change anything about my answer. Condensation of Oxygen is -183°C, Nitrogen -196°C. It’s hard to find condensation data on “air” because there’s a similar term called the “dew point” at which humidity starts condensating out of the air, but it’s probably around -190°C.

      Again, there’s basically nowhere in the known universe that’s that cold, especially on a planetary body with an atmosphere, except for here on Earth in a lab.

        Recorded temperatures at the poles of Titan indicate it’s just cold enough for oxygen to condense (-183.1 Deg. C). Unfortunately, even though cold enough, there isn’t any free oxygen detected in the atmosphere of the moon. Although it does rain methane, it’s predicted there are cryo-volcanoes, and water is as hard as stone. There are really interesting atmospheric phenomena occurring on the moon.
