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, 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.
The planet with a moon named Charon is Pluto. Charon is the largest of Pluto's five moons and it is about half the size of Pluto itself.

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)
