why is pluto not called a planet anymore?

Question

why?

Answer 1

Because he turned into a dog

Answer 2

According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit.

Pluto has been demoted because it does not dominate its neighborhood. Charon, its large "moon," is only about half the size of Pluto, while all the true planets are far larger than their moons.

In addition, bodies that dominate their neighborhoods, "sweep up" asteroids, comets, and other debris, clearing a path along their orbits. By contrast, Pluto's orbit is somewhat untidy.

Some may argue that since Pluto is called a 'dwarf-planet', it is also a planet, but it is not so.

Many astronomers think that this will not last for a long time, they think that Pluto will once again be considered a planet, but a majority of the astronomers argue that if Pluto can be termed a planet, then an asteroid Ceres can also be termed as a planet as it is also a dwarf planet.

Its still an ongoing debate, the facts may change again.

Answer 3

It is an object from the "oort cloud" which is a band of billions of icy chunks that resides at the boundary of our solar system.

The belt is what is left of the acreation process (the process of gasses becoming plannets) and comets are other members which are occasionally removed from the belt and thrown towards the sun or away from the solar system by graviational distubances. These disturbances are from our systems movment throughout the galaxy.

When pluto was discovered this system of objects was not even known. It is now understood and we have observed many of them. The object formerly known as planet pluto isnt even a stand out one of them, its not big, not small and not special.

Its basically a chunk of ice that floats about. It was a mistake that was made and we had to unmake it. So its no longer classified as such.

It was the right thing to do...there are many moons that are more planet like than pluto (and infact more earthlike than any other planet).

its still a part of the neighbourhood and it will always hold a place in our hearts. We may one day go say hi!

Answer 4

Pluto, was considered too small to be a planet anymore after the recent discovery of three other plants, even further away from the sun, that were bigger than Pluto. And after astronomers made the "regulation size" bigger than Pluto was. Pluto is now considered a dwarf planet. I personally don't agree with the dropping of Pluto from our solar system. After all, It's like saying if someone is under 4' 10", they're not a person anymore.
Hope this answers your question!

Answer 5

Because it is a lump of ice with a completely different orbit from the other planets. It more closely resembles a large comet than anything else. If we look further out in the solar system, there are many other big lumps of ice with similar orbits. If we counted all of them, there would be thousands and thousands of planets that were nothing but chunks of ice, and only eight that were large balls of rock and gas.

Answer 6

Because astonomers have finally aggreed on a definition of a planet. Pluto does not fit that definition.

Answer 7

with more new powerful telescope , we are worry to encounter
too many Pluto on the boundary of the solar system

Answer 8

They made a new word out of the name, it's plutoed, & it means to be demoted, like me losing my sight, I've been plutod!

Answer 9

Because scientists decided it shouldnt be described as one anymore.

I used to disagree with that but it is very small - its not even as big as our moon.

Answer 10

because he was SMALL..............lets face the facts guyz the scientist didnt want a small *** ball to deal with so they called pluto and told him ..............man u juz to small............f u c k off ..............U R FIRED..............u no longer fit to be a planet.

so thatz how pluto was reduced to a dwarf........................POOR PLUTO!!
