why isnt pluto a planet anymore?

Question

i miss pluto.....it was my lover :(

Answer 1

Because it doesn't dominate it's orbit.

But as for the people trying to say it still is, people tried that with Ceres as well and it didn't make Ceres become a planet then.

Answer 2

Ok well if you not might know, beyond Pluto is the Kuiper Belt. This belt contains many icy objects like comets or large objects. Now years ago we didn't really know what this belt really contained. But now we have found much more within it. Within this belt they found large objects...One of the objects even bigger than Pluto was named Eris. Due to the great confusion of all these new objects, Astronomers had to define the planet. They set new standards for what qualified to be a planet and Pluto did not fall under this. From then on Pluto along with 2 other objects (Eris and Ceres) became "dwarf planets". So Pluto is now considered part of the Kuiper Belt. Don't worry Pluto is still around but under these new standards Pluto can no longer be a planet and now flys galantly among the Kuiper Belt = ). Hope that helped

Answer 3

It is just a change in the definition of a planet. Pluto hasn't changed. The missing/lover thing indicates a severe confusion issue.

Answer 4

I just can't wrap my brain on why this question keeps cropping up. Why Pluto? Why do so many people have an emotional attachment to a chunk of ice at the fringes of the solar system? It's not even the only chunk of ice at the fringes of the solar system.

Pluto is small, cold, dark, and boring. It is the least interesting of all the bodies in the solar system. The IAU made the right call. Get over it. Pick a new favorite planet and get on with your life.

Answer 5

I miss it too, friend, I miss it, too.

When scientist first found pluto, they thought it was a planet.

As technology advanced, they've found lots of other "rocks" floating around that look like pluto. There was planet X, remember?

They found more and more rocks...and just decided that instead of naming all the lil rocks, they'd just do away with Pluto.

But, it will forever live in my heart...and when someone asks ME how many planets there are, I'll still say "My Very Excited Mother Just Served Us NINE PIZZAS!

Answer 6

When other bodies were discovered with similar properties to Pluto, and that there may be hundreds of them, the men with beards decided that it was too unwieldy to have hundreds of planets. They decided rather to change the definition and have eight.

Answer 7

Ok... It IS in our galaxy. Yes it is... The Milky Way Galaxy. And it is a member of the solar system as well...

It was determined that it didn't qualify as a planet due to it's size and other factors.
I still consider it a planet too... Why did they have to go and mess it all up by denouncing it!?

Answer 8

first of all a celestial body to be classified as a planet it should
have enough mass for its self gravity,so as to assume a hydrostatic equilibrium
it should have cleared all the cosmic debris in its neighbourhood

pluto has not cleared the cosmic debris in its neighbourhood
and also follows an eccentric orbit istead of elliptical
it overlaps the path of neptune and is too small

Answer 9

It looks like there are lots of other things just like it out there in the solar system at about that distance. They can either call all of them planets or none of them.

Answer 10

because of the fact "back on your day" (and interior the day of all people over 5 years of age) we did no longer be attentive to almost as lots relating to the image voltaic device as we do now. as quickly as all of us started analyzing lots greater products available we found out that a clean definition of "planet" had to be arise with or we'd only shop looking further and added "planets" and finally each and every youngster in third grade could be memorizing the names of a dozen or greater balls of rock and ice that only ensue to orbit the solar. back on your day we additionally theory Pluto had a million moon, Charon. all of us be attentive to be attentive to that Pluto orbits a ingredient in area exterior of itself and that Charon, Nix, and Hydra (we did no longer additionally be attentive to Nix and Hydra existed back then) orbit it to boot alongside with a gaggle of alternative Kuiper belt junk. We additionally be attentive to that there is a gaggle of junk orbiting the solar interior a similar section as Pluto. the incontrovertible fact that Pluto is not any longer a planet has no longer something to do with its length, that's an ordinary false impression. It has to do in general with the incontrovertible fact that it has no longer cleared its orbit of alternative junk orbiting interior a similar section, due in general to its susceptible gravity. If we nonetheless seen Pluto a planet we'd additionally would desire to think approximately Eris, Makemake, Sedna, Orcus and a gaggle of alternative Kuiper belt products planets, and we'd additionally would desire to think approximately Ceres, interior the asteroid belt, a planet. So we'd definitely have 13 planets a minimum of authentic there with who knows what proportion greater to be got here across. once you learn the attributes of those products with the 8 authentic planets it turns into obtrusive that none of them, Pluto coated, must be categorised jointly with the planets.
