Sedna? Deloy mentioned "Pluto." You do remember Pluto? I don't think we need to accept the current IAU's perverted definition of planets for this model. I think it's a better historical perspective to include Pluto. Sig On Sun, Feb 19, 2012 at 4:42 PM, Patrick Wiggins <paw@wirelessbeehive.com>wrote:
I had thought about that but including the dwarf planets at the same scale would have Sedna just over 2 km away. And if we scrunched Sedna's orbit into the existing 120 meter radius orbit the inner planets would be so close together and so close to the Sun as to be pretty much unobservable.
And, let's face it, if we go with brass plaques the cost of 9 for the Sun and planets seems more doable vs. 18 (or more) if we include the dwarfs.

It's unacceptable without Pluto.
