Who made the official decision to downgrade Pluto from a planet to dwarf planet?

The scientific 'community' made the decision. Pluto is considered to be too far away from the Sun to be classed as a planet of the solar system. It is now accepted to be part of the Kuiper belt.

Is mars still considered a planet?
Yes, Mars is still considered a planet, and has never been considered for a downgrade like Pluto.
Do all astronomers think that Pluto is a planet?
No. It was categorised as a dwarf planet in 2006, but not all astronomers agree with that decision.
What is the name of the planet replacing Pluto?
Nothing is replacing Pluto. Now that Pluto is no longer considered a planet, the number of official planets in the solar system is down to eight.
What planet revolves around the sun every 249 days?
That would be Pluto, but Pluto is no longer a planet, it's too small. Now it is classified as a dwarf planet. It was the source of a lot of debate over the last decade but finally a few years ago under the new definition of a planet Pluto could no longer be defined as such. I believe Dr. Neil DeGrass Tyson was largely connected with the decision of cutting Pluto off the list of Planets. I believe the decision was based mostly on the fact that there are other objects that are about the size of Pluto.
Who killed the planet Pluto?
No one killed the planet Pluto. Pluto was reclassified as a "dwarf planet" by the International Astronomical Union (IAU) in 2006 due to its smaller size and different characteristics compared to the eight classical planets in our solar system. This decision was based on scientific understanding and classification criteria.

Nothing is replacing Pluto. Now that Pluto is no longer considered a planet, the number of official planets in the solar system is down to eight.
How come there is all this trouble over Pluto being a planet or dwarf planet when they are all just planets any way?
Because for years it was thought that there were 9 planets, which included Pluto. But, in recent years it has been discovered that there are other, smaller, dwalf or minor planets which lay beyond the orbit of Pluto. Some of these dwalf planets are as big or even possibly bigger than Pluto. So, a decision had to be reached to either downgrade Pluto to the status of a dwalf or minor planet or include all of these other objects (and nobody knows precisely how many there are) into the main system of planets. If they were all included allthe minor planets into the major system of planets they would all need to be named, so the decision was taken to downgrade Pluto to simplify matters. So now there are only 8 major planets and many more, mostly un-named and undiscovered minor or dwalf planets.
Who found out that Pluto was no a planet?
It was not "found out" but a decision that was made by a panel of planetary experts to define what is a planet and what is not which "degraded" Pluto from planet status of "dwarf planet" on August 24, 2006.There are at least 44 dwarf planets known.

Did Pluto ever go around earth?
All planets (although Pluto is not considered an official planet) revolve around the sun, so it is impossible for a planet to revolve around another planet.
What was the the planet that is no longer a planet in your solar system?
Pluto, it is now a dwarf planet or planetoid.
