No. It was categorised as a dwarf planet in 2006, but not all astronomers agree with that decision.
In 2006 the IAU agreed that Pluto was a dwarf planet. Although, many people were against the idea of identifying Pluto as a dwarf planet.
If you still consider Pluto to be a planet, then the answer is Pluto, which completes one revolution around the sun in 248 years. If you agree with the downgrading of Pluto to something less than a full-fledged planet, then the answer is Neptune. The general rule is: The farther a planet is from the sun on the average, the longer it takes to complete its orbital revolution.
It is purely a matter of definition. The International Astronomical Union came up with a new definition for a planet and Pluto failed to make the cut.Before 2006, there had been no actual definition of "planet" that everybody could agree on. But with the development of new and better telescopes, teams of astronomers began finding smaller and more distant objects, and some of the teams announced that they located "the tenth planet". But many of the proposed "tenth planet" candidates were a little unusual.In 2006, the IAU convention decided that a planet must meet three criteria:It must orbit the Sun, not another planet.It must have attained "hydrostatic equilibrium", meaning that its gravity had crushed it into a spherical shape.It must have cleared the neighborhood of its orbit, so that no other objects were orbiting the Sun nearby.
No. Pluto was reclassified as a "dwarf planet" because it's a tiny ball of ice and rock significantly smaller than the Moon, gravitationally bound to Neptune, and it really makes no sense to lump it in with bodies like Jupiter and Saturn.It's really a historical accident that Pluto was ever considered a planet in the first place. People were looking for a planet to explain certain things about Neptune's orbit... it didn't seem to be moving quite right, but a planet outside Neptune's orbit about the mass of Earth would have made the calculations come out right. By sheer luck (good or bad, depending on your opinion), Pluto happened to be about where people were looking for this "Planet X".The more we found out about Pluto, the more it didn't seem to fit the equations. Measurements of its size and mass kept coming up short, and estimations changed from "about the size of Earth" to "about the size of Mars" to "about the size of Mercury" to "maybe around the size of the Moon" to "dang, this thing is tiny."Meanwhile, more careful measurements of Neptune's orbit showed that it didn't need any extra mass out there after all, it was orbiting precisely as predicted by theory.

Pluto is a planet!

If you have a meeting of minds, then you are in accord. You agree with one another.

As Pluto, a dwarf planet, is no longer counted as a planet, there are now only 8 known planets in our solar system.It remains to be seen if the discovery of extra-solar planets affects how we classify objects within our solar system. Several hundred likely planets have been detected orbiting other stars, with the possibility that there are other solar systems like our own. By late 2011, a total of 599 exoplanets had been identified and another 1235 were pending corroboration.Status of PlutoPluto is a dwarf planet in the solar system and the prototype of a yet-to-be-named family of Trans-Neptunian objects. From its discovery in 1930 until 2006, it was considered the ninth and smallest of the planets of the Solar System, both by the International Astronomical Union (IAU) and the general public. After much debate, the IAU decided on August 24, 2006 to reclassify Pluto as a dwarf planet, requiring that a planet must "clear the neighborhood around its orbit." Further observations may also affect the definition of Charon as a moon of Pluto, possibly the classification of the two as a binary planet.
One of the 68 moons in Jupiter was classifed as a planet. Some scientists came to the conclution that vb12 was the 68th moon in Jupiter. As you can see, a large porcion of the scientist were wrong. Not every scientist come to the same conclution.
You can do this by agreement, call for a meeting. And everyone should agree.
