Seriously, even Neptune gets the boot for its recently discovered trojans. I think anyone who buys into this needs to get an astronomy program, then turn on the orbits for all known asteroids. The "belt" is something of a misnomer, they're all over the inner Solar System.

I'm happy with the decision, pluto didn't deserve planetary status along wtih the other classical planets. Classifying it a dwarf planet or trans-neptunian object is just fine.

Can we at least call Pluto/Charon a double dwarf planet on the grounds that their barycenter is not within either body's mass?

If you're not happy with it, read the Footnote 1, which explicitly mentions the eight planets of the Solar system. One astronomer quipped that only it should be accepted. The wording was selected to make it more understandable to a layman (who, after all, is the one who needed the definition, astronomers were happy without it).

I preferred the definition that was bandied about last week, which would have resulted in 13 (known) planets round these parts.
I appreciate that I may be in a minority in that respect.

Reina, have you been to Hayden planetarium, in American Museum of Natural History, that one on the 72nd street west side Manhattan? They have only 8 planets there for a long time, no Pluto, very smart people work there... I'll be there in few weeks, and for sure will visit planetarium again! Hayden Planetarium: http://haydenplanetarium.org/ bu the way, here is scientific proof for only 8 planets in Solar system, big work, 22 pages, but worth reading: "What is a Planet?" (by Steven Soter, works at above mentioned place) http://arxiv.org/ftp/astro-ph/papers/0608/0608359.pdf |

First, may be know who is the "someone"? Second, this is totally, absolutely WRONG. IAU made very clear definition of planets, and said that Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune are planets. Please read this work of Mr. Soter and it be very clear to you the part of resolution which says: RESOLUTION 5A (1) ... (c) has cleared the neighbourhood around its orbit. Read this work, and it be clear as a clear day what did all those smart astronomers meant by "has cleared the neighbourhood around its orbit.": "What is a Planet?" (Steven Soter, AMNH) http://arxiv.org/ftp/astro-ph/papers/0608/0608359.pdf |

Wow. I knew that this wouldn't change anything.
Last week, we were arguing about what to call planets, and what not to call planets. This week we are arguing about what to call planets, and what not to call planets. How about next week we tackle some important issues? Like war, poverty, or the icky color my office is painted. |

So they rejected the proposal in the other thread?
I have to say, I was kind of growing on the idea of calling Ceres a planet. It would fit with the Titty-Boobs law more. But, I think I'm happier with this decision to keep the great eight planets as the exclusive members. Now, New Horizons is a mission of special importance. It is going to study one of the biggest KBOs in the solar system.

Ceres isn't just an asteroid any more. It's now a dwarf planet.
Let's hope that it (and other giant asteroids) get more publicity now.

This just in, Pluto has now changed it's name to "The object formerly known as a Planet"
In text books it name will now be replaced with a symbol ![]() ![]()

Well, the upside is that it'll increase the number of amateur astronomers who can say they've observed all of the planets.
Not sure I understand the "clearing out" bit, or the bit about the Sun. I guess a previous poster has clarified what "clearing out" is defined to mean, but including only the Sun in the definition seems strange -- any chance that was a media misconception? |

but that money could be very well invested into more imporatant scientific projects, especially after we learned that bigger KBOs then Pluto exist out there. |

maybe if we talked to Pluto, explained carefully to it the advantages of a more circular orbit which does not transgress Neptune's orbit. Poit out that there might be federal funding if it cooperates...
...oh wait, I just remembered: THE UNIVERSE DOESN'T GIVE A DAMN WHAT YOU CALL IT. silly, silly topic to get worked up over. Eight, ten, thirty six... what's the difference?

Common sense has won out. Orbitally and positionally, Pluto doesn't fit in. In the Solar System family, Pluto is the pet dog, not an equal member. We haven't lost him, he just can't eat at the table anymore.
