Thatis correct. If you count it's moon (which is approx. the same size as it) it's a double planet system, with its rotational axis more or less at the Lagrange point.
Otherwise, it's a lump of rock (a planetoid, maybe. Not quite a plant, but in the wrong place to be an asteroid and it's not quite a comet.)
And Sedna, don't get me started on that. If Pluto doesn't count, and Sedna's half the size of that...
[/astrophysicsy rant]
Is QI on again? If so, what channel and when? And is it available up here in the land of the Scots?
