Solar System Larger?
Looks like our solar system is larger than we thought.

eh, pluto is only still called a 'planet' because it has been for so long. When in fact it is simply the largest of a group of things out there called the "Edgeworth-Kuiper" objects. For many many years, pluto was simply the only one of these things we knew about. If Pluto was discovered in 2000 instead of the 30's, no way in a million years would anyone have called it a major planet, simply a big Kuiper belt object.
Then again, there is really no hard criteria for what distinguishes a minor planet from a major planet. Having a moon means nothing; there are a few asteroids that have 'moons'; Neither Mercury nor Venus have any. If we weren't hit by an object the size of mars millions of years ago, we would not have one either. The main criteria that is commonly used in the scientific world is how they were formed in the early solar system.

You know, it could be that the solar system is not getting larger . . . but rather WE ARE GETTING SMALLER !!!!!

And don't get me started on the Space Program.
Do you really want Earth to aim rockets at Uranus?
Do you want spacemen crawling around on Uranus collecting samples?
Do you?
I think not.

From the show Futurama:
<Fry (looking through a telescope)> Hey, I can see Uranus! (laughs)
<Farnsworth> No, we changed the name of that planet several hundred years ago because people were tired of all the off-color jokes.
<Fry> What's it called now?
<Farnsworth> Urectum.
I still laugh at that when I think about it.
