The planets

Via Reason Hit and Run

I was quite surprised recently when I learnt that all eight(ish) other planets could "fit" into Jupiter.

Also quite surprising is that one of Pluto’s moons is about half the size of Pluto itself, which is why some astronomers think of them as a binary planet system (or something like that).

Meanwhile astronomers are still bitterly divided over what seems to the layman like a trivial/irrelevant question of whether we have 9 planets or 10...

So much for "2001".
