Growing up, I'm sure most of us were taught in school about the facts of our solar system and the nine planets. Even though the change has happened a while ago now, I still can't help but miss little Pluto being our farthest planet way out yonder. I know ideas change as facts and new discoveries are made, but I can't help but feel a personal " Awwww :( " that Pluto's status was downgraded.

Then again, I can't possibly expect that upon new discoveries and new ideas leading to changes in perspective to be overridden by such unscientific feelings as "Oh come on, it's been considered one of the nine major planets for a long time, just let Pluto remain a planet".

But I still miss little Pluto! I wonder what other discoveries we'll learn that will change our perspective on things down the road. It's all quite exciting :D

As far as I know, Pluto is now 4 separate objects, most likely ice moons and not planets. As usual things becomes more complex and difficult to understand and comprehend the more you get to know about the same things.

Nature will always be having surprises for us. We will never get to know all the secrets that are either hidden or too far away for us to study in great detail.

I believe pluto is no longer considered a planet, because of the number of other objects of similar size out there at that distance. If you count Pluto as a planet, you have to also count another number of these distant dwarfs...


Anyways, complaints can go to "the man that killed pluto", Neil Degrasse Tyson.

And today Pluto, Dwarf Planet or not, has not 4 moons, but 5! That's more than all the inner planets combined.

One or two of the largest asteroids are larger than Pluto.

What's all this fuss about? Pluto hasn't gone away - it's still out there, where it's always been. Just got a new classification, that's all. Not like the dang Vogons slagged it to make way for a wormhole or a trans-warp bypass.

I saw the tv show he did on that. He went to Clyde Tombaugh home town. Neil actually did a lampoon of himself. At the end of the show one of Clydes daughter actually (kind of) agreed that Pluto was a dwarf planet. Neil had added Pluto back in the solar system as a dwarf planet by placeing the image back on the wall.

There are other scientist who belive a planet is any world that is round by its own gravity that orbits the sun. I hold to that definition myself.

How do we know Pluto is round? Also they take the additional step of having the planet have its own descrete oribtal zone. Pluto does not.

Pluto doesn't even orbit in the same plane as the other planets.

[quote]How do we know Pluto is round? Also they take the additional step of having the planet have its own descrete oribtal zone. Pluto does not. [/quote

The orbital zone is just part of the definition. They also say that a planet has to clear out its orbit of rocks. Earth wont even quailfy with NEO's swarming around us. Neither does Jupiter.

Unless you have accsess to studies saying Pluto isnt round. Everything Ive read to date, scientist say it is round. Plus that nice photo by the hubble that was in The Planetary report sure looks round.

Pluto, formal designation 134340 Pluto, is the second-most-massive known dwarf planet in the Solar System (after Eris) and the tenth-most-massive body observed directly orbiting the Sun. Originally classified as the ninth planet from the Sun, Pluto was recategorized as a dwarf planet and plutoid owing to the discovery that it is only one of several large bodies within the Kuiper belt.

There are two points here.

Scientifically

Pluto has been downgraded to a dwarf planet because of the discovery of other large bodies or similar size, which were not known about when it was first discovered and designated as the ninth planet.

Publicly

Nearly all of us were brought up and taught that Pluto was the ninth planet, and we have accepted that all our lives without question. Now that new scientific evidence has been discovered, we sadly have to accept that it isn't a "real" planet any more.

I think that to appease public opinion it should have a dual classification as a "dwarf" planet, and an ex ninth planet.

There were and still are many astronomers and scientsits who were ticked off when Pluto was demoted. There were many who said the stated definition was to narrow.

Well it is just a definition, and they do change over the years.
