The solar system in brass. Every planet in its correct period. Every moon in its proper station. Wind the key. Watch the cosmos obey. This is the audacity of the Enlightenment — that the universe runs like a clock.
88-day year. Swift as thought. The messenger planet races so close to the sun that astronomers once thought it had a permanent dark face.
365.25 days. The quarter-day that accumulates into a leap year — a beautiful mathematical debt the calendar pays every four years.
687 days. The red wanderer. The ancients called it the war planet. Now we know it as the rusted ghost of a warmer world.
