Welcome to Triton, one of Neptune’s moons, super-chilled and covered in frozen nitrogen snow. It would be big enough for us to live on, the question is, could we?
Triton is the largest natural satellite of the planet Neptune, and the first Neptunian moon to be discovered, by English astronomer William Lassell in 1846. It is the only large moon in the Solar System with a retrograde orbit, an orbit in the opposite direction to its planet’s rotation.
