Science said there were 9 planets, so with Chiron legally being
a planet, Plutos got to go. Because science says there can only be 9. RIGHT!

Much to my surprise, the International Astronomical Union has indeed voted on a resolution that defines exactly what a planet is and Pluto no longer qualifies. This means that Pluto is indeed not a planet any more and that our solar system no longer has the nine planets I learned about as a kid, but only eight!

Don't worry, though, Pluto is now to be known as a dwarf planet, so it's not been completely ejected from our solar system, just relabeled. The eight planets in our solar system are now, in order from the Sun outwards, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

As The Planetary Society explains, "a “planet” is now defined as a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit."

"A dwarf planet, according to the new definition, is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite."

Got it?

There are now three dwarf planets in our solar system, so Pluto isn't alone. It's joined by the asteroids Ceres and Xena (aka UB313), though more than a dozen are on the IAU's dwarf planet watch list, if you can believe it.

One key reason that Pluto has been given the boot is because its orbit is not in the same ecliptic plane as the rest of the planets and isn't circular as are the planets, but is rather "eccentric". Indeed, at certain points in its orbit, Pluto is actually closer to the sun than Neptune.

Either you're posing as a stereotypical Christian Fundamentalist, or you ARE a Christian Fundamentalist. Scientists decided Pluto wasn't a planet because astronomers reached a consensus that Pluto was just a ball of ice floating in the depths of our solar system, and not a planet. "Legally being a planet..." Wow! I didnt know there were laws regarding what is and is not a planet. American laws? Israeli laws? French laws? Which laws? No, science has never, and will never say that there can only be 9 planets. Science taught that there were 9 planets. Then they found out they were wrong, that Pluto wasn't a planet. That is science in itself. New discoveries lead to new knowledge, and the removal of things that are untrue.

YO, update buddy... there are eight planets... and science doesn't say there can only be nine planets. Get your facts right. Science orginially classified Pluto as a planet, along with eight other planets, bringing the total to nine... But science never claimed that only nine planets can exist in our solar system, that was simply how many planets there were to our knowledge. As we learned more, we revised our definition of planet, and, unfortunately, Pluto didn't make the final cut. As far as I know, nothing else did either. There was a time when Pluto was in, as were three other planets, bringing the total up to eight, but again, the definition has been refined and, as far as I know, there are eight planets, which is totally acceptable...

FYI: you spell out the numbers one through nine...

What are you babbling about? Why would atheists specifically feel bad about it? Yeah poor Pluto, but oh well, it didn't exactly leave or anything.

BTW science doesn't stay rigid on a set ideal, it changes as new things are learned and figured out...it is religion that resists change no matter what.

Also...they have decided to call it now a "dwarf planet," so...doesn't sound totally 'unplaneted' to me, so...*shrug*

I do not see any relevance to this train of thought. I feel sorry for all the children taking science in school now though, who knows how many more new planets will be discovered in the next few years?

science doesn't say that there only can be and has to be 9 planets. and charon isn't a planet because its smaller than pluto and if pluto isn't a planet a space body that is smaller than it will most certainly not be

science is constantly undergoing trial and error to jump to the best conclusions. Over time scientific facts/theories may and do change. This is because Science is based on testing and criticizing information and forming new and better conclusions as more information is gathered (i'm christian btw)

no, your an idiot

first off their are now 8 planets so that would crush your argument right their. Second science evolves with new information unlike many religions.

oh, and I am not an atheist but your still an idiot

You don't make sense. they now say that there are 8 planets. there would've been 12 if Pluto had stayed.
