14. Is Pluto the farthest planet from the Sun, or are there other planets beyond Pluto? (A K2S Question)

From The Space Library

The discovery of a new planet a bit bigger than Pluto, but quite similar to it, was announced in the summer of 2005. It is three times further from the Sun than Pluto is. There may be a few other Pluto-like planets out there, waiting to be discovered.
