Trans-Neptunian Scattered Disk Objects

I was reading this morning about Eris, the infamous object that caused all manner of trouble for Pluto's status as a “planet.”  I thought Eris was a Kuiper Belt Object but apparently it's a trans-Neptunian scattered disk object.  Who'd have thought.

The solar system refuses to be simple.  I like this diagram though and these linked-to Wikipedia entries are nice.

Oh, and I guess we're now calling Eris a dwarf planet.   (Where now is defined as 2006).

“It's headed toward that trans-neptunian scattered disk object.”

“That's no trans-neptunian scattered disk object.  That's a space station!”
