The orrery models how planets move in orbit, and it was the first of its kind made in Boston. Curator Ethan Lasser sheds light on this instrument, on display in "The Philosophy Chamber: Art and Science in Harvard’s Teaching Cabinet, 1766–1820," opening tomorrow, May 19. | Harvard Art Museums | Facebook

It works because of interlocking gears! ☀️The medium sized gears rotate the Sun, which causes the Earth to spin around it. As the small gear rotates around the large gear, the Earth rotates too - just like in our solar system! | KiwiCo | Facebook
