Cnn.com: 10th planet (?) found in our solar system I think this is pretty neat stuff. Makes you wonder how many other planets are out there that we haven't found. http://www.cnn.com/2004/TECH/space/03/15/distant.object/index.html
How many times are they going to find our solar system's 10th planet? I swear I've read that headline a half-dozen times in the last decade.
I think that as long as it's not orbiting around another planed, they might as well call it another planet. Then I can tell my children that I was around before cell phones and before planet Sedna was discovered.
I guess this could be important if this thing leaves its orbit and heads towards earth. But we still know more about the surface of the moon than we do about what lies beneath the surface of the oceans.
IIRC, beyond Pluto is the Ort Cloud and contains all sorts of stuff, which is why you keep seeing the "10th planet" headlines. But don't hold your breath. Nothing out there is going to get planet status unless it's big, has a stable, "planet-like" orbit, and, well, behaves more like the other planets than a big collection of asteroids, comets, and other stuff.
I think its neat, but it sure would suck for the 3rd graders who now have to know another planets name.
From Mori IIRC, beyond Pluto is the Ort Cloud and contains all sorts of stuff, which is why you keep seeing the "10th planet" headlines. But don't hold your breath.

Size is the only thing that maters. There are planets circling other stars that are bigger then Jupiter and have erratic orbits we could find a planet the size of Earth or larger in the Ort cloud because of it distance to the sun. there is just not a lot of light out there to detect any thing as far as a 10th planet I would like to see something the size of mars or bigger before I would call it another planet
Yes, I just saw a show on the Science Channel yesterday about planets in other star systems. Although, I thought there was the concern of anything they find out there being a permanent resident of the solar system and not just something that happened to wonder in and would fly out of the solar system? That is part of what I meant with the stable orbit comment.
I doubt "Sedna" will be recorganized as the 10th planet. It's too small. Anything bigger Sun won't be able to attract it.
