RE: new planet?

It's Sedna. And yeah, it's believed to be the first object observed in the hypothetical Oort cloud.

But it is not a planet. It is smaller than Pluto, which is still struggling to be accepted as a planet. It also orbits so far away and in an extreme ellipse (13 billion kilometers at the closest, up to 150 billion kilometers at the furthest from the Sun) that it is more likely to be recognized as an asteroid.

But the interesting thing is that there may be millions of these objects out there...
