Um...there are only eight planets. Pluto was demoted to dwarf planet status. There are now eight planets and three dwarf planets, Ceres, Pluto, and Eris. There are probably other dwarf planets waiting to be discovered though.

From the discovery of Pluto in 1930 to the establishment of a formal definition of planet in 2006, the existence of a tenth planet was speculated by astronomers and the general public alike. Tenth planets frequently appeared in fiction, and media reports of new trans-Neptunian object (TNO) discoveries used the label with some frequency. The 2006 redefinition, however, made it highly unlikely that any body will ever be termed a "tenth planet" by establishing orbital dominance as a principle and moving the number of planets back down to eight, meaning that a hypothetical ninth planet will now need to be discovered first and meet the new criteria.
During the mid-1800's when the first four asteroids discovered were considered planets, Saturn was the tenth planet.
