Hello all,

My Tellurian arrived in the mail. It's almost perfect! A few small changes and it will be perfect.

http://www.shapeways.com/modules/udesign/utils/openfile.php?id=38941&f=photos/photo4726.jpg

A Tellurian is a model of the movement of the earth and its moon in relation to the sun. This movement includes the orbit of the moon around the earth, the earth sinning on its own axis, and the orbit of the earth around the sun, while keeping it's tilt.

Soon it will be available for sale. I designed in parts to be printed in WSF material, or metal if it is approved.

Here is the product page with more pictures:

Thanks for looking!

Is it to scale?

The moon is a proper size in relation to the earth.

The sun is not to scale with the planets. If it were, the sun would be huge and unprintable. In truth, it rarely is with a tellurian or an armillary sphere. My understanding is that, at times, the size of the sun in the tellurian is supposed to represent an approximation of what one sees from the earth and thus it is represented sometimes smaller than the earth.

The most important thing about a tellurian is that is illustrates how the earth and moon move. Scale is secondary if at all important.

Here are some pictures of other tellurians to help illustrate my point:

(note: how this tellurian uses a candle to represent the sun)

I've been thinking of doing a model that moves in the first mathematically correct yet flawed version of planetary movement, where everything revolved around the earth but in swirls. It was actually accurate to find the positions, and showed true human ingenuity to make it so the Solar system actually did revolve around the earth.

Yes, waiting for metal approval does seem to require some patience, as I well know. Wink

Instead of a bulge, to counter act the weight of the Earth and Moon, have you considered making a little wire Rocket Ship?
