Pluto Options

[Mommy]

Astonomers are getting on my nerves. The other day they were arguing over whether some of our solar system's moons should be called planets instead. In fact, I read an article the other day where they were wanting to change the defintion of a planet and this new definition would mean that someday our moon would be classified as a planet. I dont know whether or not they decided on that new definition but it basically stated that any object orbiting a planet whose center of gravity falls outside the planet it is orbiting will be considered a planet. Because the moon is moving farther and farther away from the earth, it would one day become a planet under that definition. Now, they voted yesterday that Pluto isnt a planet

FYI, it's not the center of gravity of the moon itself that would make it a planet. It's the center of gravity of the combined moon-Earth system.

They've been arguing about Pluto for decades, though. While there's news on this now, the debate really isn't anything new.

thats not how it stated it in the article the other day i dont believe.


and yes, the debate has been going on for some time, but the voted and made it official
