Is Pluto still a planet?

Pluto may lose its status as a planet! Amazing what you learn on the news. However, what they did not say, was why, or how. Sometimes, I find the news coverage lacks the basics of the Ws. What, when, why, where, and who. Don’t forger the How.

This led me on a search of the net, and it revealed the following:

From two sources, but I have not included the URLs because the blog police would almost certainly remove them.

• Pluto is an unusual planet as it is made predominantly of ice and is smaller even than the Earth's Moon.

• Professor Gibor Basri, an astronomer at the University of California said that recent discoveries of large asteroids in the Kuiper belt, on the solar system's fringes, had tested the hazy definition of "planet".

If Pluto, with a diameter of 2300 kilometres, was a planet, other similar-sized bodies in the solar system should be so regarded, he said. The 1300-kilometre Quaoar, discovered last year, was the biggest find in the solar system since Pluto in 1930.

According to Professor Basri's definition, a planet must orbit a star, not another planet, and it must be round. That means it must be 700 kilometres in diameter, when gravity moulds it into a sphere, or bigger. Smaller objects are potato-shaped.

I guess he didn’t see the Star Wars episode where if you look closely you can see that the some of the asteroids are potatoes and socks… (Yah! It’s true!)

Okay then!

Do we really need to revisit this definition? Aren’t there more important things to do, like figuring out how to stop the imminent crisis in the Middle East? Or how to make cars run without petrol / diesel? Or even, how to … Oops, getting maudlin again.

Let’s start a petition to save Pluto. K?

Actually the definition of planet was recently revised by the scientific community, and Pluto is still in along with three other bodies previously considered asteroids. So by the new definition we now have 12 planets.

just in case this wasn't a rhetorical question

Latest update: Disney thinking of reclassifying Pluto - after all, other cartoon dogs are bigger and cuter.

Pluto will always be a planet in my book.

The electric car was invented years ago (1830's) but due to technological limitations companies went the way of the internal combustion engine. Check out battery electric vehicles on the wikipedia web site.

Hi

Haven't seen you in a while. Welcome back.

Actually, according to the new definition, we have at LEAST 12 plants, perhaps more.

Thing is, Pluto may not be one of them - I think there is still debate. I can't read geek, and the reporting is anything but clear. Can you explain it to me then?

Thanks,

Hugs

    I agree with ya there are much more important issues! But what the hell I'll sign the petition! Always up for a lost cause!

I agree - how can we suddenly say it's not.

As for the electric car - I heard that too, but there is a conspiracy theory that General Motors and the Oil comanys bought the patent of hte best battery and hid it. Or something. (One of my friends is a hectic conspiracy thoerist... twilight zone stuff)

Thanks - I will go to Wikipedia and get the facts. Ha ha.

    I read something quite awhile back where astrologers were speculating Pluto's planetary status. Some are suggesting that Pluto is either...

    1. A renegade moon of Neptune
    2. An asteroid
    3. The moon of an undiscovered planet. (Planet X, Vulcan, Proserpina...whatever you want to call it.)

    TheCelt- We could always go back to the good old days where we could blame everything on Saturn.

Welcome.

I personally think Saturn may be responsible for everything. Why else hide in a ring of "stuff". I mean, what is in there? Hmmmmm?

ha ha

I haven't seen the actual report yet, but I'll try to find it today.

Heree's a heavily edited copy of the IAU press release abut the new definition of planet.


The IAU draft definition of "planet" and "plutons"

16. August 2006, Prague

The world's astronomers, under the auspices of the International Astronomical Union (IAU), have concluded two years of work defining the difference between "planets" and the smaller "solar system bodies" such as comets and asteroids. If the definition is approved by the astronomers gathered 14-25 August 2006 at the IAU General Assembly in Prague, our Solar System will include 12 planets, with more to come: eight classical planets that dominate the system, three planets in a new and growing category of "plutons" - Pluto-like objects - and Ceres. Pluto remains a planet and is the prototype for the new category of "plutons."

The International Astronomical Union has been the arbiter of planetary and satellite nomenclature since its inception in 1919. The world's astronomers, under the auspices of the IAU, have had official deliberations on a new definition for the word "planet" for nearly two years. IAU's top, the so-called Executive Committee, led by Ekers, formed a Planet Definition Committee (PDC) comprised by seven persons who were astronomers, writers, and historians with broad international representation. This group of seven convened in Paris in late June and early July 2006. They culminated the two year process by reaching a unanimous consensus for a proposed new definition of the word "planet."

The part of "IAU Resolution 5 for GA-XXVI" that describes the planet definition, states "A planet is a celestial body that (a) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (b) is in orbit around a star, and is neither a star nor a satellite of a planet." Member of the Planet Definition Committee, Richard Binzel says: "Our goal was to find a scientific basis for a new definition of planet and we chose gravity as the determining factor. Nature decides whether or not an object is a planet."

If the proposed Resolution is passed, the 12 planets in our Solar System will be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313. The name 2003 UB313 is provisional, as a "real" name has not yet been assigned to this object. A decision and announcement of a new name are likely not to be made during the IAU General Assembly in Prague, but at a later time. The naming procedures depend on the outcome of the Resolution vote. There will most likely be more planets announced by the IAU in the future. Currently a dozen "candidate planets" are listed on IAU's "watchlist" which keeps changing as new objects are found and the physics of the existing candidates becomes better known.
