Pluto, UB313 (Xena) and Ceres are now considered Minor Plantets. Charon is still a moon.

sure on that? i remember hearing it had a unique orbit with pluto such that they both orbited around a point between the two instead of it orbiting pluto. maybe i'm mistaken... but is a moon still a moon if it orbits a "minor" planet?

Yes, it's splitting hairs... but we (the world) have never had a definded definition of what is and is not a planet. Oddly, we have had one for what is a moon. That was the whole point of the top 2,500 astronomers from 75 countries getting together for two weeks to hammer it out.

Now, two of the objects that at one point were cruising toward possible full-fledged planethood will join Pluto as dwarfs: the asteroid Ceres, which was a planet in the 1800s before it got demoted, and 2003 UB313, an icy object slightly larger than Pluto whose discoverer, Michael Brown of the California Institute of Technology, has nicknamed "Xena."

Charon, the largest of Pluto's three moons, is no longer under consideration for any special designation.

Brown was pleased by the decision. He had argued that Pluto and similar bodies didn't deserve planet status, saying that would "take the magic out of the solar system."

"UB313 is the largest dwarf planet. That's kind of cool," he said.

The "requirements' for something being called a planet, even when i was hardcore into such things, i remember as being annoyingly vauge. There STILL is no full consensus on which stars make up wich constelations, that'll be next i bet.

I was sort of put-off by the "pluto isnt a planet" thing, but after thinking about it, and the way solar systems form... its really not of the same "stuff" as the other planets.

Although calling it a "dwarf planet" seems sort of lame, since that still implies its a planet. Should have some seprate name like "large solar object" or something.

That's just kinda ridiculous... So were going to try to pretend Pluto doesn't exist anymore? We're not gonna tell the little kids about it?

What are they going to make of Interplanet Janet? You know, if any records of it aren't destroyed by the government.

"And Pluto, little Pluto, is the farthest planet from the sun... whoa oh..."
