Triton
If Titan had been born on the frozen rim of the system it
would have been much like this world. Triton is similar
in composition to its sunward cousin but has only a
tenuous atmosphere of nitrogen and methane. Of little
practical importance, Triton hosts a single small outpost,
the Lassel Planetary Science Centre. The Centre studies
the traumatic evolution the icy moon, its geologically
diverse landscape of cliffs and folds of ice and rock, and
the nitrogen geysers that lift dark particles many kilometres
into the starry sky.
