Scale Model of the Solar System?

I think they rounded some numbers off here, but it is a cool idea that makes science fun for a whole community :P

Hey, we have one of these in Ithaca, although the scale is really tiny. The inner solar system planets are within a block or so of one another. You do not get to do a good walk until you go see the outer planets. Also, the smaller planets are not balls like the one pictured in the CNN article, rather they are specks with an arrow pointing at them to distinguish them from dirt on the glass.

Here is a link to it:

In November 8,1997 a unique, educational monument and memorial was dedicated. Built, in part, to honor Ithaca resident and Cornell Professor Carl Sagan, the Sagan Planet Walk is a scale model of the Solar System in the midst of the City of Ithaca. The model stretches from the center of the Commons in downtown Ithaca north to the Sciencenter 1.2 km away.

We have too. The scale is five times larger than the one you mention and Pluto is six kilometers from Sun.

Which reminds me of Bode's law, according to which each planet's distance from the Sun should be twice that of the one before it (1, 2, 4, 8, 16, etc.). According to Bode's law, the Earth shouldn't be there and there should be a planet between Mars and Jupiter.

I miss Carl...even named my wolf/hybred after him Sagan

Saw an old nova and it was Kip Thorne talking about how Carl ( doing research for his novel "contact" )had poked him into defining a mechanism that would allow "faster then light " travel. Thorne not only provided an out for Sagan , but started an relatively (HEHE) new discourse on the "unallowable" and generated both some new insights into some approaches that seemingly were Verbotin in the currently accepted model of the cosmos, but at the same time reinforced some "common" sense ideas about effect proceeding causality.

I recently learned that someone very intelligent, and very dear to me, had no understanding at all of what a lunar eclipse was or of the celestial mechanics involved. I've noticed this with lots of other friends and acquaintances, as well. I had the idea that a lot of these problems could be solved if there was actually a scale model of the solar system around for them to see. I've had an idea of making one in some fashion.

Then I found something cool! There are at least a few websites that will scale things for you! All you have to do is type in the size of the Sun in either millimeters or inches, and it will tell you the size and distance of all the planets. That rocks!

I don't have the links, but I think they're easy to find if you go to Google and type in "scale model of the solar system"

Actually your wrong about that. Bode's Law is like this:

Begin with the series of numbers, where every number is twice that of the previous (except the second):

0 1 2 4 8 16 32 64 etc

Multiply them by 3:

0 3 6 12 24 48 96 192 etc

Add 4:

4 7 10 16 28 52 100 196 etc

As you can see, the Earth fits in perfectly with a distance of '10'.
This series is quite acurate. These is are the actual distances if define the distance from the Earth to the Sun as 10:

_M___V___E___M____Ast___J_____S_____U
3.9__7.2__10__15.2__26.5__52.0__95.4__191.9

This rule was invented before the discovery of Uranus, and is quite surprising that it fits quite well in the series. The asteroid belt wasn't discovered either and it fits perfectly too as it is often considered the remnants of a planet or a planet that never formed.

The rule however fails with Neptune and Pluto which are 'too close': 300.7 and 396 respectively, instead of 388 and 772

Edited to add: The numbers of the actual distances are a bit of because I typed it from a book that has a hastily added section announcing 'the newly discovered planet Pluto'. Go here: http://www.exploratorium.edu/ronh/solar_system/ and type in 100 mm for the size of the sun and you'll get more accurate numbers.

c0rbin, since you made a plea for replies I thought I should say I was going to reply to this, but all I had to say was "cool" and someone already said it.

I'm building a scale model of the solar system myself...

I plan a scale of 1:1.

I may need some help with a few of the planets....

As suggested, "Bode's Law" fits, to a degree, some of the known data.

"Bode's Law" is not, however, a law of physics.

It has been described as a "coincidence" and a "mnemonic," but it is not a physical law.

I mention this because some believers in in undiscovered planets think that Bode's law is a physical law that predicts the location of those planets.

Sorry no rent for joo. The primary residence flips the poles every few years, the mother in law cottage's ( moon) last tennent left dust everywhere and the summer cottage in the boonies ( Mars) atmosphere, which had a lifetime gaurentee, is kaput. ( I understand that it was the sub-contractors fault, but thats not my problem)
