Triton is currently about 4,337,390,970 kilometres from Earth, or 28.99 astronomical units, which puts a one-way radio signal 4.0 hours out. It is 29.88 astronomical units from the Sun.
Neptune’s largest moon and the only big moon orbiting backwards, a captured world with nitrogen geysers and a young, icy surface.
Likely a captured Kuiper Belt object, a sibling of Pluto.
