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. patrick On 19 Feb 2012, at 16:09, D P Pierce wrote:

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:

Not that my opinion should count for much, but I back Patrick on this. Keep it simple and informative for it's target audience. It's not suppose to be a complete model of the solar system though clearly it is designed to be accurate in the information that it does contain. I think it's a great idea the way it is Patrick. However, it might appease Pluto's armies to include an additional plaque that includes the names and relative size and distances of the dwarf planets.

I think we should consider Pluto et al. only if there's a plaque for the asteroid belt. Otherwise, it's time we got over sentiment and moved on. (This is a reversal of my previous position but I have come to see the folly of counting every sizable orbiting rock as a planet.)

Make the refractor dome itself the Sun. Then Jupiter is basketball sized and the other planets aren't microscopic. We can discuss materials in committee. I have some ideas. I move that this SLAS issue be moved off-list. On Feb 19, 2012 8:44 PM, "Joe Bauman" <josephmbauman@yahoo.com> wrote:

Hi Chuck (et al), I like the idea of the dome as the Sun. For a moment after reading your suggestion I flirted with suggesting we paint the dome yellow but then I came to my senses. But I did get a chuckle as it reminded me of someone (Joan?) years ago saying they wanted to paint their refractor yellow and add a large Chiquita Banana logo. :) With the dome as the Sun we could buy several balls to be stored at SPOC and used to compare the sizes of the various planets to each other and to the Sun. Though, if I've done my math right, some of those balls are going to be pretty small (see data at the bottom of this message). However, I'd like to see this remain a topic here on the list, meaning by "topic" the various ways of possibly constructing such an orrery and not dredge up the whole Pluto mess which caused so much strife here before. All, BTW, are welcome to attend the SPOC committee meeting on the 25th (http://slas.us/displayevent.asp?EventID=1896). All are also welcome to take part in the SPOC cleanup(s) which I think will be scheduled soon. Clear skies, patrick On 19 Feb 2012, at 21:03, Chuck Hards wrote:

Relative sizes of the planets to scale. Assumes the Refractor House dome to be 5 meters (500 cm) in diameter. Object Diameter Scale Sun 1,392,000 500.0 Mercury 4,879 1.8 Venus 12,103 4.3 Earth 12,756 4.6 Mars 6,792 2.4 Jupiter 142,984 51.4 Saturn 120,536 43.3 Sat rings 275,000 98.8 Uranus 51,118 18.4 Neptune 49,528 17.8
Sounds good. As long as we don't get into the Pluto debate, talking about the scale and construction of an orrery is perfectly apropriate. The sun is just huge compared to the planets, there's no getting around it. C. On Sun, Feb 19, 2012 at 10:31 PM, Patrick Wiggins <paw@wirelessbeehive.com>wrote:
