A newly discovered neighbor in the solar system

Astronomers are claiming they have discovered a tenth planet in our solar system. However, there's some controversy over whether this "kuiper" object on the outer edge of the solor system and others like it, including Pluto, should be classified as "planets" since they are so different from the other planets in the solar system. In any case, I think it's fascinating when these new discoveries are made. Our own planet contains so many wonders and amazing sites to see. It's incredible to think that an infinite number of other, perhaps much more amazing planets, lie out there in the universe completely untouched and unexplored by humans (of this earth at least).
