It is now widely accepted that Pluto should not be classified as a planet, because more bodies more massive than it were discovered beyond its orbit. Also, it seems that it has characteristics similar to other objects in the Kuiper belt.

When was Pluto disscovered not a planet?

It was not so much a discovery that Pluto wasn't a planet, so much as a general concensus that it shouldn't be called a planet anymore. Over the past decade, astronomers have discovered several bodies beyond the orbit of Pluto that are in fact larger (for example, Eris.) They realized that there were probably many more they hadn't discovered yet and that the term planet was impractical for Pluto since it was so small and there were so many similar sized objects orbiting the Solar System. Eris was probably the final blow to Pluto's status. It is larger than Pluto and for a long time astronomers called it the solar system's "tenth planet''. In the face of this discovery and the fact that many other similarly sized objects had been found, the International Astronomical Union decided to formally define the word "planet" for the first time in 2006 and in the process effectively demoted Pluto.


What is the planet farther away from the sun?

its unusual but it is planet X. you may think im wrong but me is 98% sure *** All of them. Since Pluto follows an irregular orbit an a different axis than the other planets, it's relative distance to the obits of other planets is always in flux. If you meant to ask which planet is sometimes farther from the Sun than Pluto, the answer is Neptune.


What is Pluto called now?

It is still known as Pluto, even though it was downgraded to a dwarf planet and given a number. So really we should call it 134340Pluto.


Why is Pluto a planet?

Pluto use to be a planet but not anymore.Scientists have figured out that Pluto ism uch to small to be a planet.So now we just call Pluto a dwarf planet.A dwarf planet is kind of like a planet.It is a VERY small sized planet.A regular planet is a normal sized or a big sized planet.If the planet is too small then it is considered as a dwarf planet.

Why do astronomers consider Pluto a dwarf planet?

Pluto is too small to be an actual planet and is, therefore, a dwarf planet. Astronomers cannot call every rock orbiting a star a planet, and so have removed Pluto's title as a planet.

Why do they call Pluto the double planet?

They call Pluto the double planet because rather than Charon simply orbiting Pluto, the two objects revolve around their common center of mass, which lies outside of Pluto.
