The International Astronomical Union has just striped planetary status from pluto with their 2006 Redefinition of a planet.

 

I personally think that Pluto shouldn't be considered a planet it is no more a planet than many other objects in the farther regions of our solar system... what do you guys think?

If Pluto is a planet we will have some more than nine ...if we mess with the same criteria.

 

BTW, can anybody please ask Pluto if he wants to be a planet or not? I mean, if he is one, then it's possible some day humans will land on it....and who want's uninvited visitors?

I think it is, some of the planets are just giant rocks that have an orbit around the sun, pluto is a giant rock and it orbits around the sun, so i concider it a planet

 

A planet is more than just a giant rock that orbits a star...

 

This is the old defination of a planet... Pluto, Ceres, Charon, and 2003 UB313 all fit in it.

 

A planet [1] is a celestial body that (A ) is in orbit around the Sun, and (B ) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape.

 

This is the new defanition of what a planets is.

Since i can remember Pluto has been a planet. You can't change it now. That's just going to mess with all of our heard. LOL.

But that's typical science.... changing its mind every 50 years.

 

Well if we leave pluto as a planet then there would be a new 5th planet... Ceres. This would make pluto the 10th or 11th due to Pluto's moon, Charon fiting under the old planet defintion aswell. Also 2003 UB313 or "Xena" would need to be named 12th planet.

Would you want all that confustion or would you rather just drop Pluto?

I'll always think of it as a planet at heart lol.

 

(C ) has cleared the neighbourhood around its orbit. <- I really need to brush up. Now if earth and mars intersected orbits .. which would be considered a planet and which would not? Or did I get the definition wrong? =0\

I would assume either the larger of the two or the one with a more circular orbit... but i'm not sure.

All this talk on is or is it not. Just wait some the scientists to tell us. You guys are stressing too much.

 

rogabean I'm a Scorpio but I don't really think if Pluto was found out to be a large alien ship it would matter to me. It has no affects on my life and so changes nothing. Cool info though as I didn't know that.

 

I need to unsubscribe to this topic.

They already classified it as a sub planet. They had a 7 member conference on this not too long ago. They also said that there is another dozen or so planets/sub planets past Pluto but didn't talk all that much about them.

Think about all the shops that have the solar system maps and that big ball with 9 smaller balls spinning around them.

 

Hell, I didn't even think about that... that sucks.

 

I remember in high school (?... maybe college) there was talk that Pluto doesn't really count. "It's more like an escaped moon." or "Pluto is just a big comet with a low eccentricity." It stuck in mind for some odd reason.
