This is pure crap. Galileo must be rolling over in his grave. Why the hell do we have to classify everything? We have 9 planets, 10 if an object is truly past Pluto. There is no discussion for me IMO.

I am just coping my blog article to here so I don’t have to retype every thing.

The Eight Planets
Over the past week the debate has continued and the astrologers I mean astronomers have determined a new definition of a planet.    “(1) A planet1 is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.”   
With that Pluto has been stricken from the planet list because it dose not “clear the neighborhood around its orbit” this is because the orbit of Pluto crosses that of Neptune’s.  If that is the case why then is Neptune still a planet? It overlaps Pluto’s orbit.

Pluto is still however being called a dwarf planet under the new definition of a dwarf planet.

“(2) A dwarf planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape2, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.”

Apparently these dwarf planets are still not planets; making the list of Sol’s planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and possibly Neptune.

It seems to me that the new decision on what is a planet was made more for history and culture then for science, because you could still find a celestial body that is in orbit around the Sun with mass sufficient to overcome rigid body forces so that it assumes a … nearly round shape and has cleared the neighbourhood around its orbit that is still smaller than Pluto, and must by definition be called a full blown planet.  So how is it that we call Pluto a dwarf planet, and this smaller thing a full planet.

I thought that this was an interesting quote form the article I read on the subject.

He had argued that Pluto and similar bodies didn’t deserve planet status, saying that would “take the magic out of the solar system.”

This really just means that it was too hard for the astrologers to figure out our horoscopes with 12 planets to worry about.

 

Edit ---

After rereading the new definition it struck me that it said a celestial body that is in orbit around the Sun (Sol I’m assuming) instead of a star. This could mean that a object orbiting another star could not then be a planet.

Later-

Nice try, but Neptune has coerced Pluto's orbit to be a subharmonic of its own (1.5 times its own), so it is 'cleaned up' nearly as much as if it were in a lagrange point.

I think this is a mere oversight, of course planets can orbit other stars.

Yes… I just thought that it was funny because they did make it clear in last weeks definition that it was to be orbiting a star.

Also I saw this video on msn.

I though that it is was funny because it says that the Milky Way now has 8 planets.

Seems kind of silly. I mean, am I going to point to a chart with nine planets on it
and say to the grand kids, "I remember when we had nine planets and
they were good enough fo us"?
We've got nine of the things, leave 'em be.

I don't like the 'clears its orbit' citeria at all, but I agree with 8 planets.

How about... "massive enough to potientally have a significant atmosphere" for planets, and "massive enuogh to be round" for planetoids/dwarf planets? Sorta fuzzy, but no more than 'cleaing orbits'.

Just a bunch of technicalities. I think the dwarf planet thing makes sense seeing as how we've been spotting so many asteroids and ex-moons that could qualify as planets recently.

You realize that cutting out planets that don’t have an atmosphere would cut out Mercury.

That is the only reason this happened. If Pluto didn't have a lot of friends around, it'd be fine. But at the rate they're finding them, we'd expect to find around 100 pluto-scale objects out in the kuiper belt.

In other words, it wouldn't by MVEMJSUNP, it would be MVEMJSUNPABCDEFGHIJKLMNOP QRSTUVWXYZABCDEFGHIJKLMNOP QRSTUVWXYZ ABCDEFGHIJKLMNOP QRSTUVWXYZ ABCDEFGHIJKLMNOP QRSTUVWXYZ.

I would have rather had that then the definition we got… I don’t think this is the end of the planet debate as there is nothing stopping other scientific communities from making there own definition of what a planet is.

If we are going to have dwarf planets they should have given a size qualifier.  As it is you could still have my full planet that is smaller than Pluto so there are still holes in there plan.

I think they're just prejudiced against little peo... er, planets.

We'll miss you, Pluto.
