I'm no astronomer, but someone who knows much more about this stuff than I do (no great claim) says the new criteria that redefined Pluto as not-a-planet, could also be applied to disqualify our (most of us, anyway) home planet!
I encourage everyone to research this definition (I'd have said Google it - but I don't want to violate trademark). I hope I'm wrong. Does Earth meet the new, stricter definition of planet?
If not, what ARE we?!?
I'm no astronomer either but I doubt that anyone would even want to come close to demoting our precious planet Earth.
Tom whined about tradition and Pluto being a planet. Well...if Earth lost it's status then he'd be bitching, along with many astronomers and the rest of the world.
The earth was the center of all things and everything moved around us.
You can prove this for yourself. No matter where you go, no matter how you get there, everywhere you look (at that moment) you are the center of everything.
Under all the definitions they were throwing around the Earth was always a planet. The definitions that they were debating that made Pluto a planet also made Pluto’s moon a “planet”, and our moon a “planet”. Basically everything round in the sky was to be called a “planet”. The reason to call Pluto a planet are largely the emotional connections people have with Pluto.
The main reason Pluto is a planet in the first place is largely due to Percival Lowell's hype about the predicted location of Planet X. Even though there is no such thing, No one really questioned Pluto’s planet-dom-ness. Until now.
The center of gravity between the Earth and the Moon is inside the Earth's crust. So the Earth is a planet and the moon orbits it.
