After reading Mike Brown, CalTech university, website: I am now convinced that the IAU did the correct thing to demote Pluto and 2003 UB313 to a dwarf planet. The IAU used the best scientific definition available for a planet. Mike Brown is probably not happy about this decision, but he says it is the best scientific defintion.
When we were kids, back in the ice ages, ha ha, they didn't know about the Kuiper Belt Objects, and so couldn't truly understand Pluto in a true context. I hope the IAU doesn't change this definition again at their 2009 meeting. I think the world needs to accept the fact that there are 8 planets, and everything else in solar system. |

and was surely far more interesting visually than Neptune, " Voyager 2 measured the current value of Uranus's rotation, right? When was it first known? At least, that it rotated on its "side"? |

Probably the first clue was the ring and moon system, which was known prior to Voyager's visit. Interestingly, in terms of the most known "natural" satellites (those which formed with the planet,and were not captured later), Uranus is king of the heap.
