No. It was categorised as a dwarf planet in 2006, but not all astronomers agree with that decision.
No. Most follow the new IAU definition of a planet which excludes Pluto.
The meeting of astronomers at the International Astronomical Union (IAU) where Pluto was redefined and classified as a "dwarf planet" took place in August 2006. During this meeting, the IAU established new criteria for what constitutes a planet, leading to the conclusion that Pluto did not meet all the necessary requirements due to its size and other factors.
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 did not disintegrate. It is still there. The only thing that has changed is a new formal definition of a planet, and Pluto did not make the cut.
Because 2 years ago the astronomers found out that Pluto is not a planet. It is too small to be a planet. Some authorities are still rooting for Pluto! They still consider it is a planet, though very small.
No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.

the planet because Pluto the planet was there before all of us
Pluto did not disintegrate. It is still there. The only thing that has changed is a new formal definition of a planet, and Pluto did not make the cut.
Pluto was considered a planet until fairly recently. It has now been established as belonging to the kuiper belt, rather than our solar system - and thus has been 'downgraded' to a dwarf planet.
No, they are not. Pluto doesn't meet all of the requirements to be considered a planet.
Because 2 years ago the astronomers found out that Pluto is not a planet. It is too small to be a planet. Some authorities are still rooting for Pluto! They still consider it is a planet, though very small.
First of all, Pluto is not a planet. It was considered a double planet because its largest moon Charon is half its size.
