leave Pluto alone

[8bits]

i agree pluto shouldn't be a planet

[Lata]

Well it's not a planet, but hey! It's got to be kept as a planet for posterity really, since it's been one for nearly 100 years and we all hate change.

I'm not bothered what they say about it really

[JayDoubleU]

Its not a planet lol I watched the programe on BBC 2 last week, very interesting.
Pluto is smaller than our moon and several other moons in our solar system. Added to which if u brought it closer to the sun , its surface would started to evaporate, giving it a tail ..now wot else has theses characteristics !?

The ruling body on this stuff will decide in Sepetember this year wot the proper definition of a planet is (there is no prorper definition as it stands) , we may end up after that with 8 planets or up to 20. Madness.

yep, shouldn't be a planet methinks.

Could the shape of the oribit around the sun be used to judge if an object is a planet.

e.g. commets orbit the sun but have different shape orbits to that of "planets" in the same way Plutos orbit brings it inside that of neptune on some occaisions i.e. eliptical...????

Also extra-solar planets found around other stars in other solar systems have some very strange orbits compared to our own solar system. This should also effect the deffenition of a planet.

Also our own Mercury has a very stange orbit in that it actully travels in a straight line though space but only appears to be orbit our sun. As our sun bends space-time around itself Mercury travells through this bent space...


Just a thought.. I dont know...

Better change that title Phokus!
It's inaccurate

yeah Shiva man, I think that a big part of the decision relateds to the fact that Pluto doesn't orbit in the plane of hte solar system but Ceres does, showing that they have different origins so ought not be in the proper planet family. Also Pluto and Charon system is actually a double-planet system since they are similar size (the only other planet with a moon nearly so big in relation to it is Earth). Anyway the whole hting is a bit dodge since Ceres is loads smaller than the Moon and isn't even properly round like a planet should be.

Here are some diameters just so you get an idea how teeny the dwarves are:

Earth 12756 km
Mercury 4879
Mars 4200 km

Moon 3476 km
2003 UB313 3000 km
Pluto 2274 km
Charon 1172 km
Ceres 950 km

Ah well it's all pedantry really, I am sure that the only people who will be affected are kids who now only have to learn name of the planets up to Neptune.

[elektrovert]

I think the whole thing is pretty cool!!
Who would have thunk it??

Our generation has witnessed so much change and advancement in society/technology!
and now there's a major change in the solar system.

It's all good.

[Statto]

bye bye pluto

[_cform]

was nice while it lasted

Interseting!!

Should there not be a planet in between mars & jupiter, where the astroid belt lies?? Perhaps an un-formed or destroyed planet??

p.s nice to finally meet you at Traffic on Sunday

[elektrovert]

There is! a new dwarf planet!

[JayDoubleU]

yes yes downgraded indeed , bye bye to Pluto the joker planet

[Shiva]

there is! a new dwarf planet!

ahh!!



doea this mean anything spherical in the astroid belt is a "dwarf planet"?

[Lata]

I dunno guy, if we are talking about any bits of rock just chucking about in the solar system, we'd get nowhere since all of the gas giants have huge satellite rings made up of some massive bits of rock adn we have to draw the line somewhere.

I suppose this is the way of the world - the Solar System is classified by those geeky crew who did astrophysics at uni and not by us junglist peeps who obviously should be controlling important matters like this!



HEY SHIVA - I met you at Traffic!?!?! WHO ARE YOU?

Zoe Introduced you to me - I was with Roderick (Blackeye) - My name is James

Awww Hi James, how are you? Yeah it was wicked to meet you and the other crew, Roderick, Peter and Thusara? I hope to catch you all again when I get back to England! You lot have to come to Greece some day!

[SETI]

this doesn't mean anything whatsoever, at least to astrologers who count Pluto in their systems, to their benefit.

[Lata]

I was wondering this - since Pluto was only discovered in 1930, how did astrologers decide to include it in their stuff? Since I thought that astrology was some ancient chinese/indian/greek/other people? stuff that was written ages ago no?

[SETI]

Eastern/Vedic astrology does not include the outer planets past Saturn.. Pluto has been watched by Western astrologers ever since it's discovery in 1930 and it's effects were noted (United States' natal sun sign= tropical Cancer, where Pluto was located at the time of its discovery.. astrologers like to point to the development of nuclear energy and the great depression to Pluto's influence on America at that time as starting points to identifying that planet's aspects).
