With an average temperature of around 34 kelvin, Triton is extremely cold. Currently, it has a thin mostly nitrogen atmosphere with a pressure of around 1 Pa. However, its surface has large deposits of nitrogen ice. This leads me to a few related questions.

* Do we know how much nitrogen ice is on Triton?
* If all the nitrogen ice on Triton thawed, how thick would its atmosphere be?
* Will Triton thaw naturally, and have a thicker atmosphere, in the future as the Sun's luminosity increases?
* If so, would its atmosphere be stable over a long period of time?
* In the far future, perhaps as the Sun turns into a red giant, would Triton be warm enough to have liquid water?
