The discovery of other similar objects to Pluto in more recent years has meant that astronomers either had to keep adding planets to the list, or we had to redefine what a planet actually was. In 2006, a new definition for a planet was established. It had to be approximately round, it had to orbit the sun and it had to have cleared its neighbourhood of all other objects - so that at that distance from the sun, there were no other sizable bodies. Pluto is not large enough to have done the latter, while all other remaining planets have, so it was downgraded to a dwarf planet. There are now eight planets recognised and five Dawrf planets, of which Pluto is one.
Pluto is not a planet because it is not the dominant object in the region around its orbit.
So, it fails to satisfy this criterion and is not classed as a planet, by the definition established in 2006.
Pluto is now considered to be a dwarf planet along with Ceres, Eris, Haumea and Makemake.
No it is. But sometimes the scientists say that its not. But for the time being it is.
Pluto is not a planet because it is to small to be a planet.
It is too small to be a planet.It is now a star
no Pluto is not a planet
cause its a dog you bonga
Pluto, it is now a dwarf planet or planetoid.
neptuneNeptune is the closest to Pluto. Uranus is the second closest planet to Pluto. Saturn is the third closest planet to Pluto. Jupiter is the forth closest planet to Pluto. Mars is the fifth closest planet to Pluto. Earth is the sixth closest planet to Pluto. Venus is the seventh closest planet to Pluto. Mercury is the most furthest away from Pluto. The Sun and the moon are not considered as planets. The planet Pluto is also not considered as a planet.
"Planet X" was originally a term for a hypothetical TENTH planet, BEYOND Pluto. Also, Pluto is no longer considered a planet.
Pluto is no longer considered a planet, it is now classified as a "Dwarf Planet". As a planet or a dwarf planet, Pluto was the smallest in our solar system. Mercury is now the smallest recognised planet. Pluto's equatorial diameter is 2,274 km. Mercury's equatorial diameter is 4,880 km.
Charon, Nix and Hydra are the 3 moons of Pluto. Pluto is no longer considered to be a planet, but is classified as a dwarf planet.

Pluto is a rocky world. Pluto is now reclassified as a dwarf planet.
Pluto is a dwarf planet
dwarf planet Pluto
Pluto is a planet!
Pluto is not a planet
no Pluto is the smallest planet in the worl and Pluto is also the outer planet
Neptune. It would be Pluto, but Pluto is a dwarf planet ( a planet that was a planet, but decided that it wasn't a planet)
Pluto is not a planet, but it is a dog from Mickey Mouse. Pluto, is rather a dwarf planet, because it is not big enough to be a planet.
pluto is no longer a planet because some scientists believed that pluto no longer reched the requirments to be a planet, meaning pluto is to small to be a planet and is now considered a dwarf planet.
