From its discovery in 1930 until 2006, Pluto was counted as the Solar System's ninth planet. In the late 20th and early 21st centuries, however, many objects similar to Pluto were discovered in the outer solar system, notably the
scattered disc object Eris, which is 27% more massive than Pluto.
[10] On
August 24,
2006 the IAU
defined the term "planet" for the first time. This definition excluded Pluto, which the IAU reclassified as a member of the new category of dwarf planets along with
Eris and
Ceres.
[11] After the reclassification, Pluto was added to the list of
minor planets and given the
number 134340. The thing is that ploto was founded by gailee and it should stay that way. Pluto may just be a over- excessive ball of rock and ice but to some people like me its more than just that its a planet. And my opinion is that pluto is a planet no matter how small. I dont really care how many times people scream at me saying" PLUTO IS NOT A PLANET ANYMORE!"
