Wider zones that pricked his scars  

This is everywhere: that a new planet(oid) has been discovered, about 2x as far out as Pluto and not quite as big. There's plenty of talk about whether the new object (they're calling it Sedna, after the Innuit goddess of the sea) is really a planet, and about the implications for Pluto's somewhat controversial status as such.

What I haven't seen though is any word on whether this new planet/thingy has the same elongated, z-adjusted orbit that Pluto has, or whether it behaves more like the other 8 undisputed planets. This would certainly seem relevant to the question of planethood, and to our reconception of the solar system. I guess they haven't known about it long enough to make any generalizations about its orbit?

MORE: My astronomy fix answers half of the question: Sedna's orbit is so elliptical that its distance from the sun varies between 6 and 84 billion miles. A single revolution takes it about 10,500 years.
