No need to demonstrate, i know exactly what you mean, but i dont agree thats a valid reason to classify it as a planet, now if they where closer in size its a different question
You may aswell be saying that the CG is the planet and pluto and charon are its moons, i am sticking with pluto being the planet because its the dominant one and Charon is the one that would appear to make the orbit arround the other if you use Pluto as the focus, charon would make the circle

just above the dimensions of Charon it says (and i agree) that its the satellite |
I would call Pluto and Charon a sister-planetoid system myself. |

At most, it should be classified a planetoid. But then Ceres in the asteroid belt would have to be called a planetoid as well. |
So because we share our orbit with the moon and compared to many other planets the moon is very similar in size to earth does that mean that the moon is our sister planet, hmm nah
do you work for nasa and have some secret info about some sort of probe to pluto that was kept secret, cos it seems your the only one who knows the composition of pluto and charon |
Actually, some people would call the moon our sister planet. It is unusually large. |

No, don't be silly. I'm only 13 years old, and I'm Australian too. I just read all the stuff I said in a book on astronomy.
No the moon isn't our sister planet for two reasons:
1. It orbits the centre of gravity of the Earth, which is in the centre of the Earth, and has its own (weaker) centre of gravity. Pluto and Charon share the same centre of gravity and it is between them.
2. The moon is a lot less than half Earth's size. And it's (both comparatively and proportionally) a lot further away from Earth than Charon is from Pluto.
Check your facts before you go off being a smart@rse, OK? |
Actually, the Moon orbits the centre of gravity of the Earth/Moon system, which is inside of Earth but not exactly at the centre. The Earth also orbits this centre of gravity. |

lol, there were a massive news about this in oct,2002, they HAVE FOUND THE 10TH PLANET, HOW DID U MISS IT, HERE IS A BIT from independant.co.uk (UK NEWSPAPER)
A billion miles away, the world of giant Quaoar is the frozen limit
By Charles Arthur Technology Editor
08 October 2002
One billion miles beyond the solar system's most distant planet, four billion miles from the Sun, astronomers have discovered a massive object. "Quaoar" (pronounced kwah-o-wahr,) a frozen world measuring 800 miles across, is the biggest mass found orbiting the Sun since the discovery of Pluto in 1930.

On the news back then all we knew was there was something with a high enough gravity field that it detectably altered the orbit of pluto, now we have actually detected it with telescopes, thats why we can say its definatly a new planet, it could have been a dense part of the kupier belt |

Quaoar is NOT a planet. |

We all knew that. But there was a huge debate on whether Quaoar should be classified a planet or an ice dwarf, and I think they decided to call it an ice dwarf. |

In my book there are 8 planets, an asteroid belt and an ice dwarf belt. Pluto is just the largest and nearest ice dwarf.
