Actually, Pluto is considered a double planet: Pluto/Charon. There are
some who think Pluto would be better classified as a large asteroid or
comet rather than as a planet. Some consider it to be the largest of the
Kuiper Belt objects (also known as Trans-Neptunian Objects). There is
considerable merit to the latter position, but historically Pluto has been
classified as a planet and it is likely to remain so, as witness this IAU
press release:


The "Planet X" notion goes back quite a ways, too:


And, since 1983, we've got a new contender, a dark star called Nemesis
