But clockwork representations of the universe can still be very cool, Besides their considerable aesthetic charm, they show makers engaged with the big and little questions around them. And this craft goes back a long way. At least to Ancient Greece with the Antikythera mechanism. That's a wild story.
Orrery makers in our own century would have their hands full with updates. A few years back we had the first new planet adapted as part of the solar system since Pluto in the 1920s. Then they tried rounding out our new 10-planet solar system with asteroid Ceres and Vulcan, a near-Mercury planet no one had ever actually seen. Then it all collapsed and we wound up with an eight planet system.
