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.

_____________
Actually, neither its size nor the angle of its orbit to the equatorial plane is a problem. One part of the current definition of planet is that a body must have cleared its orbital neighborhood of debris. Pluto spends most of its extremely long year [248 earth years] among the countless other objects in the Kuyper Belt, and therefore it has NOT cleaned up its orbital neighborhood. However, Pluto is still the wonderful and interesting object it has always been. It is a Kuyper Object, and a dwarf planet.

∙ 11y agoThe notion of "planet" has ceased to be a meaningful theoretical concept.
Since antiquity, it was assumed that there were a small number of "planets", and astronomical theories reflected this. For example, Kepler assigned great significance to the fact that there were five planets and five platonic solids.
More recently, we learned what the planets were, and that there were probably thousands of them. It made no theoretical sense to treat them all as one kind of thing, or to teach children to learn some arbitrary subset of them.
Today we can categorize objects in the solar system according to their location and origin. In this scheme, the solar system consists of
1) The Sun
2) Giant Planets (Jupiter, Saturn, Uranus, Neptune)
3) Terrestrial Planets (Mercury, Venus, Earth, Mars)
4) Minor Planets (Ceres, Pluto, Eris, Asteroids, Meteors, Kuiper-belt objects)
5) Comets

What do you call a frozen ball of dust and gas revolving around the sun?
A frozen ball of dust and gas revolving around the sun could describe the planet Pluto. The planet, Pluto, was downgraded to a frozen ball dust and no longer considered to be a planet to scientists and astronomers.
What is Pluto larger than?
Pluto is not larger than any planet it is the smallest planet that why it is call a dwarf planet.
How old is Pluto and why do they call Pluto a dwarf planet?
Pluto has been declined as a planet because of its size it is the smallest planet in the solar system that scientists have found.
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.
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.
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.
What do you call a frozen ball of dust and gas revolving around the sun?

How old is Pluto and why do they call Pluto a dwarf planet?
Pluto has been declined as a planet because of its size it is the smallest planet in the solar system that scientists have found.
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.
Why is Pluto no longer a planet?
because Pluto is like an asteroid it is so tiny

What do astronomers call Saturn?
"Saturn" of course, but also they call it a "gas giant planet".
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 did Walt Disney call Mickey Mouses dog Pluto?
Pluto was named after the planet, Pluto, which had been discovered by the time his character was created.
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.
