Animation of the surface of Triton, Neptune's largest moon, with Neptune and the Sun in the sky. Triton is a dense, rocky moon that orbits Neptune in the opposite direction to the planet's rotation. This means that it must be a captured body from the nearby Kuiper Belt, a region of rocky bodies including Pluto. It orbits Neptune at a distance of around 355, 000 kilometres, taking just under six days to complete one orbit. Despite extremely cold surface temperatures of around 40 Kelvin (-233 degrees Celsius), it is geologically active, with volcanoes erupting liquid nitrogen and other voltiles. It also exhibits seasonal changes, with the Sun-facing pole warming up and releasing gases into its tenuous nitrogen-carbon monoxide atmosphere.<br>Restrictions: | |
