From this site:
“This is an orrery I made to help explain to my children why we have so much light in the summer and not nearly enough in the winter (we live in Alaska). No attempt was made to get relative sizes, distances, or the orbit periods correct. Rather, this model shows the inclination of the earth’s axis and why it causes the seasons.”
I love orreries and armillary spheres and clocks, so this makes me terribly happy.
An orrery built in the attic of a highly unusual Victorian house features prominently in the second half of my favorite book, John Crowley’s Little, Big. TRUE.
