There are a number of objects larger in size than Pluto beyond it but they are not classified as planets.

Pluto, the last planet to join the heavenly pantheon, became the first to leave it. The status of Pluto had been under discussion for some time, but with the discovery of 2003 UB313, nicknamed Xena, the question became acute, for it seemingly had as much right as Pluto to be called a planet.
On August 24, 2006, the International Astronomical Union surprised the world by voting in a new definition of planet, one that would exclude Pluto and bring the total number down to eight. (There had previously been been strong speculation that the redefinition would bring the total up to 12 instead of down.)
Pluto was instead classified as a dwarf planet, along with Ceres and the aforementioned Xena. The main difference between a dwarf planet and the real thing is that the dwarf variety has not cleared the area of its orbital path.
This redefinition met with a wave of protests from those who wanted to see the ninth planet grandfathered in, including but not limited to supporters of the late Clyde Tombaugh, who discovered Pluto in 1930. His widow, however, said he would have been accepting of the IAU's decision since "he was a scientist" and understood that astronomers had to take into account newly discovered objects in the Kuiper Belt (where Pluto is located).
But opponents of Pluto's demotion remain unconsoled and have generated a thriving industry in T-shirts, mugs and other memorabilia. Among the many slogans of this movement was one which played on the mnemonic for the names of the erstwhile nine:
"My! Very educated morons just screwed up numerous planetariums."

It's implausible to have an object larger than Pluto lurking beyond its orbit, but they have found a couple. For example, the new "dwarf planet" Eris orbits farther than Pluto. There's a whole mess of objects is the solar system's Oort Cloud that could be potentially larger, but we haven't been able to detect them yet.

The astronomers recently changed the classification of a planet.
Pluto is no longer considered a "planet" under the new international standard. They have some other sort of name for it now, but there are other bodies that are outside pluto's orbit.
Oh, and they made the change about pluto because of it crosing uranus's orbital path I think.

After the planet Pluto(now theories say that even Pluto itself is nota planet) stretches the Kuiper zone(full of asteriods).Some scientists agree that they have found the 10th planet,greater in diameter than Pluto.Discussions still occur...

oh yes there are so many... but as a new fact has come uf.. they are cancelling the planet pluto from the solar system so sm day people may ask whether there is any planet beyond naptune...

Your question is a bid vague. I assume you mean one that is orbiting our sun. There could be, because pluto is quite a recent discovery. There are billions of other suns out there, with, no doubt, planest orbiting them.
