Welcome to Pluto!
Pluto, farthest away, coldest, and an eccentric orbit. My kind of planet. It's orbit has brought it in perihelion inside Neptune's orbit until 1999. Pluto's presence after the gas giants has many theories surrounding it, including it's an escaped satellite of Neptune, or an asteroid that just happened to fall into orbit. But both of these are unlikely, especially the asteroid considering it's spherical, has an atmosphere, as well as seasons. It's only satellite is Charon, which is almost the size of Pluto itself.
