More Planetary Scheming

Well, after clarification, and discussion, most scientists now accept the nomenclature of 'dwarf planet'. The reclassification of Pluto has been accepted, and Xena officially named "Eris". This reclassification allows for old Ceres to become a dwarf planet. That's a move up from minor planet. Now, we have 4 gas giants, 4 terrestrial, and 3 dwarf planets. The disagreement comes when you number the planets. The IAU definition says there are only 8. Some say there are now 12+. This is very similar to the 19th century, when asteroids were first discovered. The number grew so quickly, most scientists chose to count only the main, historical planets.

No matter what the IAU says, I still say there are still thousands of planets. If I taught science in school, I'd teach the 12 noteworthy planets, and divide them into three categories. After that, I'd touch on the types of dwarf planets (asteroids and plutinos), and why they aren't considered part of the 8 by the IAU.

They're a bunch of overpaid assmonkeys, anyhow.

Mars - Venus - Earth - Mercury - Jupiter - Saturn - Uranus - Neptune... er...

"My Very Educated Mother Just Served Us Nine... DAMNIT!"

They ruined it. *sigh*

This is the very reason they took poor Pluto away from us. To prove, once more, that half the bs you learn in school is not going to be used in your adult life.

Do you suppose Pluto will no longer go by 'Pluto', but rather by a punctuation mark... you know, "The planet formerly known as Pluto."?

=) *giggle*

lol... Mercury is the first, Mars is the 4th.

...just sayin'.

And yes, they are overpaid assmonkeys. I wish I were an overpaid assmonkey.

Astronomy is always going to be the science of imagination. It'll never be the science you use everyday at work. BUT... the concepts that work in it, are the laws of physics that control everything around us, everyday.

I liked having a cartoon character as a planet. I vote we change Mars to 'Marvin' after the Martian on Bugs Bunny cartoons if we can't have Pluto anymore.
