Much like the solar systems we painstakingly produce, this is a students model we found online from another part of the world which we've vastly improved by a little ingenuity, metallic paint, art images from old masters (Atlas and the Hesperides), antique gels, many coats of varnish and many many hours of work. These models are expensive and hard to find just in their natural state but we have established a steady source. The gears move the earth and moon around the sun. This is designed as a students model to illustrate the earths rotation around the sun and the moons rotation around the earth.It is 16.5 inches across and approximately 11.5 tall, so it's a big piece and it makes an impact in a room. But they are lovely and there will only be a handful of these in existence.
