Although the universe works in a different way from mere clockwork, it can be visually represented using an intricate series of gears, and here's an example of that concept by watchmaker Richard Mille. To be unveiled next month in Singapore, it's called the Planetarium Tellurium, a one-of-a-kind machine simulating the motion of the solar system that's accurate to within one degree of rotation every 7.7 years.
Not only do each of the planets rotate around the Sun, all but Mercury rotate on their own axes. Made of titanium, steel, brass, gold, silver and red corundum, it's not the kind of instrument you can just pick up at the local watchmaker; this grand mechanism costs more than $1 million to build. One thing's for sure: It's certainly cheaper than launching an orbital telescope to observe other planets.
