It's Official - From the BBC news site
I know Wolverine has mentioned the passing of resolution 5A on another thread, but for the announcement would it be an idea to use this thread?

No, dwarf planets (Pluto, 2003 UB313, etc.) that orbit beyond Neptune form a new class of objects.

“a celestial body that is in orbit around the sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a ... nearly round shape, and has cleared the neighborhood around its orbit.” Then what does the overlapping orbit have to do with it? Pluto is automatically disqualified because its oblong orbit overlaps with Neptune’s. Is that because it hasn't cleared Neptune from it's orbit? I think a better explaination is in order. It was unclear how Pluto’s demotion might affect the mission of NASA’s New Horizons spacecraft, which earlier this year began a 9˝-year journey to the oddball object to unearth more of its secrets. Yep; the science of Pluto isn't valid anymore. Charon, the largest of Pluto’s three moons, is no longer under consideration for any special designation. Is Charon still considered a moon if Pluto isn't a planet? Is there a definition of a moon? (that'll probably be the next controversy) |

Resolution 6B not passed, i.e. they're not officially called "Plutonian objects".

Pluto is not a planet, nor is Charon. The definition of a satellite remains open, as well the definition of planets beyond the Solar System.

Is a Dwarf star not a real star then? I don't think it resolves much. It certainly doesn't detract from the fact that Pluto is a system which we should try and find out as much as possible about.
