planetarium that shows the relative placement of Mercury, Venus, Earth, Mars, Jupiter, and Saturn around the sun.
40mm
$25,000 - $30,000
Some advice though... if you have one of these, please never let it wind down and always keep it in a winder... cause then you'll have to resent the planetarium.,. and what a chore that would be!
