I'll tell you what look back up to the OP and there is a link now to CalTech's page on the planetoid and for the second bit you can check your upcoming show listings or watch John Stewart this week.

Look I have the actual commercial from John Stewart aired on Comedy Central on my DVR right now, and while it totally derails this thread just so you can have proof that will be here for you if you dare watch comedy central in the mean time, I'spend some time finding you the link you have just got to have for Lord knows what reason....

A recently-discovered dwarf planet, named Sedna, has an extra-long and usual elliptical orbit around the Sun. Sedna is one of the most distant objects yet observed, with an orbit ranging between 76 and 975 AU (where 1 AU is the distance between the Earth and the Sun). Sedna's orbit is estimated to last between 10.5 to 12 thousand years. Sedna's discoverer, Mike Brown of Caltech, noted in a Discover magazine article that Sedna's location doesn't make sense. "Sedna shouldn't be there," said Brown. "There's no way to put Sedna where it is. It never comes close enough to be affected by the Sun, but it never goes far enough away from the Sun to be affected by other stars."

Hiya Red, Jon Stewart probably did mention a 'tenth planet.' You're right it's called Sedna. It's from this article...Sun's Nemesis Pelted Earth with Comets, Study Suggests. It's pretty bad title, huh? The article is way more interesting...
