      Pluto is now a dwarf planet, but we do think that it is very similar to some of the moons of the outer planets, like Neptune’s moon Triton or example. Many of these icy bodies must live out around the edges of our solar system, and so Pluto was re-labelled as a dwarf planet – otherwise, if we eventually find say 400 more objects like Pluto, we would have a lot of planets to remember!
