Triton is one of the few moons that is geologically active. It has volcanoes and geysers. The geysers shoot 5 miles high into Triton's atmosphere. The volcanoes create smooth volcanic plains. Triton also has craters. Triton's atmosphere is mainly made up of Nitrogen with some with some Methane Gas. The temperature on Triton is really cold, at -393 degrees fahrenheit. It is the coldest object in our solar system.

Triton moves in a retrograde orbit and has a synchronous rotation around Neptune. Retrograde means Triton moves in the opposite direction as Neptune. Synchronous means one rotation takes as long as one orbit. Triton orbits Neptune every 5.88 Earth days. Astronomers think that Triton was once part of the Kuiper Belt and was pulled into Neptune's orbit by it's gravity. In about 3.5 billion years, Triton will come way to close to Neptune's orbit and will break apart, causing Neptune to have rings.
