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.

Ok, first of all, there is no Pluto anymore....... at least, it's not a planet. There is a new planet, and they haven't named it yet, so they call it Planet X. Personally, I disagree with them taking Pluto out of the gang, since I have always used the My Very Entergetic Mother Just Sent Us Nine Pizzas..........

UB313 (Eris) would have been the tenth planet (because it was bigger than Pluto), but instead Pluto was dropped and we only have 8 planets.

rkjr1999 is right. seeing as we dropped pluto, the 9th planet, there isnt really any hope of getting a 10th planet. it took them 76 yrs to realise pluto wasnt a classical planet. only a "dwarf" planet

The International Astronomic Union (IAU) has officially determined that there are only 8 true planets in our solar system.

I consulted with my 15yr. old son, and we agree with the person who talked about the UB313 title.
